In Hinduism
Ayurveda (science of life)
Nityatva (नित्यत्व):—Perpetual

Āyurveda (आयुर्वेद, ayurveda) is a branch of Indian science dealing with medicine, herbalism, taxology, anatomy, surgery, alchemy and related topics. Traditional practice of Āyurveda in ancient India dates back to at least the first millenium BC. Literature is commonly written in Sanskrit using various poetic metres.
Shaivism (Shaiva philosophy)
Nityatva (नित्यत्व) refers to “eternality”, according to the Īśvarapratyabhijñākārikā III.2.12.—Accordingly, “But when, through realizing [that the divine] qualities such as all-pervasiveness and eternality (nityatva) apply to oneself, by having the experience of the [real] “I” whose nature is [unqualified] freedom—[an experience] pointed out by the guru’s instruction and other methods that I have explained—[and] having therefore emerged as it were from [identification with] the objective knowables of the Void etc., and [as a result] abiding [in one’s real nature], then that is the [transcendent] state [called] the Fourth. [...]”.

Shaiva (शैव, śaiva) or Shaivism (śaivism) represents a tradition of Hinduism worshiping Shiva as the supreme being. Closely related to Shaktism, Shaiva literature includes a range of scriptures, including Tantras, while the root of this tradition may be traced back to the ancient Vedas.
Kama-shastra (the science of Love-making)
Nityatva (नित्यत्व) refers to “that which is constantly (being practiced)” (i.e., “sexual activity”), according to the Vātsyāyana’s Kāmasūtra: a Sanskrit text from the 2nd century dealing with eroticism, sexuality and emotional fulfillment in life belonging to Kāmaśāstra (the ancient Indian science of love-making).—Accordingly, “[Objection]—Some learned men say that as Dharma is connected with things not belonging to this world, it is appropriately treated of in a book; and so also is Artha, because it is practised only by the application of proper means, and a knowledge of those means can only be obtained by study and from books. But Kāma being a thing which is practised even by the brute creation, and which is to be found everywhere (nityatva), does not want any work on the subject. [Answer]—This is not so. Sexual intercourse being a thing dependent on man and woman requires the application of proper means by them, and those means are to be learnt from the Kāma Śāstra. The non-application of proper means, which we see in the brute creation, is caused by their being unrestrained, and by the females among them only being fit for sexual intercourse at certain seasons and no more, and by their intercourse not being preceded by thought of any kind”

Kamashastra (कामशास्त्र, kāmaśāstra) deals with ancient Indian science of love-making, passion, emotions and other related topics dealing with the pleasures of the senses.
Shaiva philosophy
Nityatva (नित्यत्व) refers to the “eternity” (of the triad of Śiva, Puruṣa—soul, and Māyā—primal matter), according to Bhaṭṭa Rāmakaṇṭha’s 10th-century Tattvatrayanirṇayavivṛti—a commentary on the 7th-century Tattvatrayanirṇaya by Sadyojyoti which discusses philosophical aspects of Śiva including the theories of Puruṣas (souls), Māyā (primal matter) and Mala (the innate impurity afflicting souls).—The term nityatva (eternalness) is ascribed specifically to the triad of Śiva, Puruṣa (the soul), and Māyā (primal matter). These entities alone are said to persist without being subject to creation or destruction—even during mahāpralaya (the great dissolution)—while all other tattvas (levels of reality or categories of being) are ultimately non-eternal and become reabsorbed.
Shaiva philosophy is a spritiual tradition within Hinduism that includes theories such as the relationship between the Atman (individual soul) and Siva, the nature of liberation (moksha), and the concepts of maya (illusion) and shakti (divine energy). Saiva philosophy teaches that union with Shiva can be achieved through knowledge, devotion, and spiritual practice. It encompasses major branches like Shaiva Siddhanta and Kashmir Shaivism.
In Jainism
Jain philosophy
Nityatva (नित्यत्व) refers to “changelessness”, as used in the Anekāntajayapatākā-prakaraṇa, a Śvetāmbara Jain philosophical work written by Haribhadra Sūri.—[Cf. Vol. I, P. 17, l. 8]—According to the Jainas absolute nityatva is a pure fiction. Nityatva which is possible is only relative. It is one which is in the midst of change. The Vedāntins thus are at one with the Jainas in so far as they trace sthiratva or anvitatva in the midst of change. But as they do not attach much value to this relative nityatva and lay more emphasis on the absolute nityatva than on the other, they may be classed with the Vaiśeṣikas who define nitya as “apracyutānutpannasthiraikasvabhāvam”.
