Chapter 3 - Evolution and Reincarnation

The amazing achievements of modern science have been opening every day new gates of wisdom and slowly bringing human minds nearer and nearer to the ultimate reality of the universe. The fire of knowledge, kindled by science, has already burnt down many dogmas and beliefs, held sacred by the superstition of the past, which stood in the way of truth-seeking minds. In the first place science has disproved the theory of the creation of the universe out of nothing by the action of some supernatural power. It has shown that the universe did not appear in its present form or come into existence all of a sudden only a few thousand years ago, but that it has taken ages to pass through different stages before it could reach its present condition. Each of these stages was directly related to a previous stage by the law of causation, which always operates in accordance with definite rules. The phenomena of the universe, according to science, are subject to evolution, or gradual change and progressive development from a relatively uniform condition to a relative complexity. From the greatest solar system down to the smallest blade of grass, everything in the universe has taken its present shape and form through this cosmic process of evolution. Our planet earth has gradually evolved, perhaps out of a nebulous mass which existed at first in a gaseous state. The sun, moon, stars, satellites and other planets have come into existence by going through innumerable changes produced by that evolutionary process of the cosmos. Through the same process plants, insects, fishes, reptiles, birds, animals, man, and all living matter that inhabit this earth have evolved from minute germs of life into their present forms. The theory of evolution says that man does not come into existence all of a sudden, but is related to lower animals and to plants, either directly or indirectly. The germ of life had passed through various stages of physical form before it could appear as a man. That branch of science, which is called Embryology, has proved the fact that ‘man is the epitome of the whole creation’. It tells that the human body before its birth passes through all the different stages of the animal kingdom, such as the polyp, fish, reptile, dog, ape, and at last, man. If we remember that nature is always consistent, that her laws are uniform and that whatever exists in the microcosm exists also in the macrocosm, and then study nature, we shall find that all the germs of life which exist in the universe are bound to pass through stages resembling the embryonic types before they can appear in the form of man.

In explaining the theory of evolution, science says that there are two principal factors in the process of evolution; the first is the tendency to vary, which exists in all living forms whether vegetable or animal; the second is the tendency of environment to influence that variation, either favourably or unfavourably. Without the first, evolution of any kind would be absolutely impossible. But the cause of that innate tendency to vary is still unknown to science. Upon the second depends the law of natural selection. The variation must be adapted to favourable conditions of life; consequently, either the germ of life will select suitable environments or vary itself in order to suit the surrounding conditions, if they are unfavourable. But the agent of this selective process is the struggle for existence, which is a no less important factor. Thus evolution depends on these three laws: tendency to vary, or variation, natural selection, and struggle for existence. Science tries to explain through these three laws the physical, mental, intellectual, moral and spiritual evolution of mankind. But the theory of evolution will remain unintelligible until science can trace the cause of that innate ‘tendency to vary’ which exists in every stage of all living forms.

If we study closely we find that man’s ‘self’ consists of two natures, one animal and the other moral or spiritual. Animal nature includes all the animal propensities, desire for sense enjoyments, love of self, fear of death and struggle for existence. Each of these is to be found in lower animals as well as in human beings, the difference being only in degree and not in kind. In a savage tribe the expression of this animal nature is simple and natural, while in a highly civilized nation it is expressed not in a simple and straightforward manner, but in an artful and refined way. In a civilized community the same nature working through varied device, policy and plan brings the same results in a more polished form. In the struggle for existence, amongst lower animals and savage tribes, those who are physically strong, survive and gain advantage over those who are physically weak; while, in the civilized world, the same result is obtained, not by displaying physical force, but by art, diplomacy, policy, strategy and skill. Various kinds of defensive and offensive weapons have been invented to conquer those who are less skillful in using them, although they may be physically stronger. The simple expression of animal nature which we notice in savages and lower animals, by the natural process of evolution has gradually become more and more complex, as we find in the civilized nations of the world. The energy of the lower human nature is spent chiefly in the struggle for material existence.

But there is another nature in man which is higher than this. It expresses itself in various ways, but on a higher plane. Love of truth, mastery over passion, control of the senses, disinterested self-sacrifice, mercy and kindness to all creatures, desires to help the distressed, forgiveness, faith in a supreme Being and devotion; all these are the expressions of that higher moral and spiritual nature. They cannot be explained as developed from animal nature by means of the struggle for material existence. For these qualities are not to be found in lower animals, although the struggle for existence is there. The moral and spiritual nature of human beings cannot be traced as the outgrowth or gradual development of the animal nature. There is a dispute among the evolutionists as to the method of explaining their cause. Some say that these higher faculties have evolved out of the lower ones and have developed by variation and natural selection; while others hold that some other higher influence, law or agency is required to account for them.

Professor Huxley says: “As I have already urged, the practice of that which is ethically best—what we call goodness or virtue—involves a course of conduct which in all respects is opposed to that which leads to success in the cosmic struggle for existence. In place of ruthless self-assertion, it demands self-restraint; in place of thrusting aside or trending down all competitors, it requires that the individual shall not merely respect, but shall help his fellows; its influence is directed not so much to the survival of the fittest as to the fitting of as many as possible to survive. It repudiates the gladiatorial theory of existence. It demands that each man who enters into the enjoyment of the advantages of a polity shall be mindful of his debt to those who have laboriously constructed it, and shall take heed that no act of his weakens the fabric in which he has been permitted to live. Laws and moral precepts are directed to the end of curbing the cosmic process, and reminding the individual of his duty to the community, to the protection and influence of which he owes, if not existence itself, at least the life of something better than a brutal savage” (Evolution and Ethics, pp. 81-82.).

Prof. Calderwood says: “So far as human organism is concerned, there seem no overwhelming obstacles to be encountered by an evolution theory, but it seems impossible under such a theory to account for the appearance of the thinking, self-regulating life distinctly human”. Thus, according to some of the best thinkers, the explanation of the moral and spiritual nature of man as a development of the animal nature, is quite insufficient and unsatisfactory. The theory of natural selection in the struggle for existence cannot explain the cause of the higher nature of man. We cannot say that a theory is complete, because it explains many facts. On the contrary, if it fails to explain a single fact, then it is proved to be incomplete. As such, the theory that cannot explain satisfactorily the cause of the moral and spiritual nature of man cannot be accepted as a complete theory. That explanation will be considered as complete which will explain most satisfactorily all the various manifestations of the animal, moral and spiritual nature. Moreover, supposing the ‘tendency to vary’ has evolved into the moral and spiritual nature of man, science does not explain the cause of that tendency to vary, nor how animal nature can be transformed into moral and spiritual nature. Is that ‘tendency to vary’ indefinite, or is it limited by any definite law? Science does not say anything about it.

The explanation of the theologians, that the spiritual nature has been superadded to the animal nature by some extra-cosmic spiritual agency is not scientific, nor does it appeal to our reason.

Now, let us see what Vedanta has to say on this point. Vedanta accepts evolution and admits the laws of variation and natural selection, but goes a step beyond modem science by explaining the cause of that ‘tendency to vary’. It says: “There is nothing in the end which was not also in the beginning”. It is a law which governs the process of evolution as well as the law of causation. If we admit this grand truth of nature, then it will not be difficult to explain by the theory of evolution the gradual manifestation of the higher nature of man. The tendency of scientific monism is towards that end.

Some of the modem scientists who hold the monistic position have found out the same truth which was discovered long ago by the Vedantic philosophers in India. J. Arthur Thomson, an eminent English scientist of the present day, in his book on The Study of Animal Life says: “The world is one, not two-fold, the spiritual influx is the primal reality and there is nothing in the end which was not also in the beginning”. But the evolutionists do not accept this truth. Let us understand it clearly. It means that that which existed potentially at the time of the beginning of evolution has gradually manifested in the various stages and grades of evolution. If we admit that a unicellular germ of life or a bioplasm, after passing through various stages of evolution, has ultimately manifested in the form of a highly developed human being, then we shall have to admit the potentiality of all the manifested powers in that germ or bioplasm, because the law is “that which exists in the end existed also in the beginning”. The animal nature, higher nature, mind, intellect, spirit, all these exist potentially in the germ of life. If we do not admit this law, then the problem will arise: How can non-existence become existent? How can something come out of nothing? How can that come into existence which did not exist before? Each germ of life, according to Vedanta, possesses infinite potentialities and infinite possibilities. The powers that remain latent have the natural tendency to manifest perfectly and to become actual. In their attempt they vary according to the surrounding environments, selecting suitable conditions or remaining latent as long as circumstances do not favour them.

Therefore, variation, according to Vedanta, is caused by this attempt of the potential powers to become actual. When life and mind began to evolve, the possibilities of action and reaction hitherto latent in the germ of life became real and all things became, in a sense, new. Nobody can imagine the amount of latent power which a minute germ of life possesses until it expresses in gross form on the physical plane. By seeing the seed of a Banyan tree, one who has never seen the tree cannot imagine what powers lie dormant in it. When a baby is born we cannot tell whether he will be a great saint, or a wonderful artist, or a philosopher, or an idiot, or a villain of the worst type. Parents know nothing about his future. Along with his growth certain latent powers gradually begin to manifest. Those which are the strongest and most powerful will overcome others and check their course for some time; but when the powers that remain subdued by stronger ones get favourable conditions they will appear in manifested forms. As, for instance, chemical forces may slumber in matter for a thousand years, but when the contact with the re-agents sets them free, they appear again and produce certain results. For thousands of years galvanism slumbered in copper and zinc, which lay quitely beside silver. As soon as all three are brought together under the required conditions silver is consumed in flame. A dry seed of a plant may preserve the slumbering power of growth through two or three thousand years and then reappear under favourable conditions. Sir G. Wilkinson, the great archaeologist, found some grains of wheat in a hermetically sealed vase in a grave at Thebes, which must have lain there for three thousand years. When Mr. Pettigrew sowed them they grew into plants. Some vegetable roots found in the hands of an Egyptian mummy, which must have been at least two thousand years old, were planted in a flower-pot, and they grew and flourished. Thus, whenever the latent powers get favourable conditions, they manifest according to their nature, even after thousands of years.

Similarly, there are many instances of slumbering mental powers. After remaining dormant for a long period in our normal condition, they may, in certain abnormal states—such as madness, delirium, catalepsy, hypnotic sleep and so forth—flash out into luminous consciousness and throw into absolute oblivion the power that are manifesting in the normal state. Talents for eloquence, music, painting, and uncommon ingenuity in several mechanical arts, traces of which were never found in the ordinary normal condition, are often evolved in the state of madness. Somnambulists in deep sleep have solved most difficult mathematical problems and performed various acts with results which have surprised them in their normal waking states. Thus we can understand that each individual mind is the storehouse of many powers, various impressions and ideas, some of which manifest in our normal state, while others remain latent. Our present condition of mind and body is nothing but the manifested form of certain dormant powers that exist in ourselves. If new powers are roused up and begin to manifest the whole nature will be changed into a new form. The manifestation of latent powers is at the bottom of the evolution of one species into another. This idea has been expressed in a few words by Patanjali, the great Hindu evolutionist who lived long before the Christian era.^[1] In the second aphorism of the fourth chapter (see “Raja Yoga” by Swami Vivekananda, p. 210) it is said, “The Evolution into another species is caused by the in-filling of nature.”

The nature is filled not from without but from within. Nothing is superadded to the individual soul from outside. The germs are already there, but their development depends upon their coming in contact with the necessary conditions requisite for proper manifestation. We sometimes see a wicked man suddenly become saint-like. There are instances of murderers and robbers becoming saints. A religionist will explain the cause of their sudden change, by saying that the grace of the Almighty has fallen upon them and transformed their whole nature. But Vedanta says that the moral and spiritual powers that remained latent in them have been roused up, and the result is the sudden transformation. None can tell when or how the slumbering powers will wake up and begin to manifest. The germ of life, or the individual soul as it is ordinarily called, possesses infinite possibilities. Each germ of life is studying, as it were, the book of its own nature by unfolding one page after another. When it has gone through all the pages, or, in other words, all the stages of evolution, perfect knowledge is acquired, and its course is finished. We have read our lower nature by turning each page, or, in other words, by passing through each stage of animal life from the minutest bioplasm up to the present stage of existence. Now we are studying the pages which deal with moral and spiritual laws. If any one wants to read any page over again he will do it. Just as in reading a book, if anybody feels particularly interested in any page or chapter he will read it over and over again and will not open a new page or a new chapter until he is perfectly satisfied with it. Similarly, in reading the book of life, if the individual soul likes any particular stage, he will stay there until he is perfectly satisfied with it; after that he will go forward and study other pages. One may read very slowly, and another very fast; but whether we read slowly or rapidly each one of us is bound to read the whole book of nature and attain to perfection sooner or later.

According to Vedanta, the end and aim of evolution is the attainment of perfection. Physical evolution of animal life reached its perfection in human form. There cannot be any other form higher than human on this earth under present conditions. Il is the perfection of animal form. From this we can infer that the tendency of the law of evolution is to reach perfection. When it is attained to, the whole purpose is served. Do we see in nature any other higher form evolved out of the human body? No. Shall we not be justified if we say that the end of physical evolution is the attainment of the perfection of animal form? Again as the purpose and method of neural laws are uniform throughout the universe, the end of intellectual, moral and spiritual evolution will be attained when intellectual, moral and spiritual perfection are acquired. Intellectual perfection means perfection of intellect; and intellect is perfect when we understand the true nature of things and never mistake the unreal for the real, matter for spirit, non-eternal for eternal, or vice versa. Moral perfection consists in the destruction of selfishness; and spiritual perfection is the manifestation of the true nature of spirit which is immortal, free, divine and one with the Universal Spirit or God. Evolution attains to the highest fulfilment of its purpose when the spirit manifests perfectly. The tendency of nature is to have perfect manifestation of all her powers. When certain powers predominate they manifest first while the others remain dormant. As we find in the process of evolution, when animal nature manifests perfectly the moral and spiritual nature remain latent. Again when moral and spiritual nature manifest fully, the animal is in abeyance. It is for this reason we do not find expressions of moral and spiritual nature in lower animals or in those human beings who live like them. Man is the only animal in whom such perfect expressions of moral and spiritual nature are possible.

When the individual soul begins to study its spiritual nature, its lower or animal nature is gradually eclipsed. As the higher nature becomes powerful the lower nature dwindles into insignificance; its energy is transformed into that of the higher nature, and ultimately it disappears altogether and rises no more. Then the soul becomes free from the lower or animal nature. There are many stages in the higher nature, as well as in the lower. Each of these stages binds the individual soul so long as it stays there. As it rises on a higher plane the lower stages disappear and cease to bind. But the moment that any individual, after passing through all the stages of the spiritual nature, reaches the ultimate point of perfection, he realizes his true nature which is immortal and divine. Then his true individuality manifests. For lack of true knowledge, he identified himself with each stage successively and thought that his individuality was one with the powers which were manifested in each stage. Consequently, he thought by mistake that he was affected by the changes of each stage. But now he realizes that his real individuality always remained unaffected. He sees that his true individuality shines always in the same manner, although the limiting adjuncts may vary. As the light of a lamp appears of different colours if it passes through glasses of different colours, so the light of the true individual appears as animal or human when it passes through the animal or human nature of the subtle body. The subtle body of an individual changes from animal nature through moral and spiritual into divine. As this gradual growth cannot be expected in one life we shall have to admit the truth of reincarnation, which teaches gradual evolution of the germ of life or the individual soul through many lives and various forms. Otherwise the theory of evolution will remain imperfect, incomplete and purposeless. The doctrine of reincarnation differs from the accepted theory of evolution in admitting a gradual but continuous evolution of the subtle body through many gross forms. The gross body may appear or disappear, but the subtle body continues to exist even after the dissolution of the gross body and re-manifests itself in some other form.

The theory of reincarnation when properly understood will appear as a supplement to the theory of evolution. Without this most important supplement the evolution theory will never be complete and perfect. Evolution explains the process of life, while reincarnation explains the purpose of life. Therefore, both must go hand in hand to make the explanation satisfactory in every respect.

James Freeman Clarke says: “The man has come up to his present state of development by passing through lower forms, is the popular doctrine of science today. What is called evolution teaches that we have reached our present state by a very long and gradual ascent from the lowest animal organizations. It is true that the Darwinian theory takes no notice of the evolution of the soul, but only of the body. But it appears to me that a combination of the two views would remove many difficulties which still attach to the theory of natural selection and the survival of the fittest. If we are to believe in evolution let us have the assistance of the soul itself in this development of new species. Thus science and philosophy will co-operate, nor will poetry hesitate to lend her aid (Ten Great Religions II, p. 120). Evolution of the body depends upon the evolution of the germ of life or the individual soul. When these two are combined the explanation becomes perfect.

The theory of reincarnation is a logical necessity for the completion of the theory of evolution. If we admit a continuous evolution of a unit of the germ of life through many gross manifestations then we unconsciously accept the teach-ings of the doctrine of reincarnation. In passing through different forms and manifestations the unit of life does not lose its identity or individuality. As an atom does not lose its identity or individuality (if you allow me to suppose an atom has a kind of individuality) although it passes from the mineral, through the vegetable, into the animal, so the germ of life always preserves its identity or individuality although it passes through the different stages of evolution.

Therefore, it is said in the Bhagavad Gita, as in our ordinary life the individual soul passes from a baby body to a young one and from a young to an old, and carries with it all the impressions, ideas and experience that it has gathered in its former stage of existence and reproduces them in proper time, so when a man dies the individual soul passes from an old body into a new one, and takes with it the subtle body wherein are stored up all that it experienced and gathered during its past incarnations. Knowing this, wise men are never afraid of death. They know that death is nothing but a mere change from one body into another. Therefore, if any one does not succeed in conquering the lower nature by the higher, he will try again in his next incarnation after starting from the point which he reached in his past life. He will not begin again from the very beginning, but from the last stage at which he arrived. Thus we see that reincarnation is the logical sequence of evolution. It completes and makes perfect that theory and explains the cause of the moral and spiritual nature of man.

The reader ought to know that the doctrine of evolution was known in India long before the Christian era. About the seventh century, B.C., Kapila, the father of Hindu Evolutionists, explained this theory for the first time through logic and science.

Sir Monicr Monicr Williams says: “Indeed if I may he allowed the anachronism, the Hindus were Spinozitcs more than 2 000 years before the existence of Spinoza; and Darwinians many centuries before Darwin; and Evolutionists many centuries before the doctrine of Evolution had been accepted by the scientists of our time and before any word like Evolution existed in any language of the world.” Hinduism and Brahminism, p. 12.
