Samadhi out of balance brings much reverie

J3 Samadhi out of balance brings much reverie.
K1 The characteristics of its beginning.

Sutra:

Further, in this state of samadhi the good person sees the disintegration of the form skandha and understands the feeling skandha. With no new realization immediately ahead of him, and having lost his former status as well, his power of wisdom weakens, and he enters an impasse in which he sees nothing to anticipate. Suddenly a feeling of tremendous monotony and thirst arises in his mind. At all times he is fixated in memories that do not disperse. He mistakes this for a sign of diligence and vigor.

Commentary:

Further, in this state of samadhi the good person who cultivates the Way sees the disintegration of the form skandha and understands the feeling skandha. With no new realization immediately ahead of him, and having lost his former status as well, his power of wisdom weakens. Going forward, there is nothing new to attain; and behind him, the state where he dwelled before is also gone. His wisdom is inadequate now, and he isn't as bold and keen as before. This is a case of suddenly advancing and then suddenly retreating in one's skill. And he enters an impasse, a place where he is about to fall, in which he sees nothing to anticipate. He does not feel or see anything.

Suddenly a feeling of tremendous monotony and thirst arises in his mind. His feeling is one of enormous monotony, dryness, and thirst. He feels everything is meaningless and boring, and he is thirsty because he needs to be moistened by the water of the Buddhadharma. He feels he is drying up and withering away because, for him, there is nothing at all. This is similar to the way ordinary people who do not cultivate start to feel lonely and bored. This loneliness and boredom are sure to lead to trouble, the same old trouble. I did not intend to bring this up, but because I'm afraid people might not understand, I will still talk about it. It is as when a woman thinks about a man. She keeps thinking about him until she feels incredibly anxious and restless. When men think about women, they also have this feeling of restlessness. They are lonely and bored, as if they have lost something which they cannot find. At all times he is fixated in memories that do not disperse. It is the way a man and a woman who are lovesick for each other keep thinking and thinking about each other and never forget. He mistakes this for a sign of diligence and vigor. This state of fixation on thoughts that don't disperse appears to him to indicate vigor.

K2 Giving the name and instructions to awaken.

Sutra:

This is called 'cultivating the mind but losing oneself due to a lack of wisdom.' If he understands, then there is no error. This experience does not indicate sagehood.

K3 Showing how confusion will certainly bring a fall.

But if he considers himself a sage, then a demon of memory will enter his mind. Day and night it will hold his mind suspended in one place. Lacking proper samadhi, he will certainly fall.

Commentary:

Within the states of the feeling skandha, this is called "cultivating the mind but losing oneself due to a lack of wisdom." You don't have any wisdom. But don't worry about having no wisdom, for if he understands, then there is no error. If you realize that it's only a state, then there is no problem. But if you don't understand, and you are always getting attached to emptiness and caught up in stillness, if you are always lost in reverie, then you will wither away without any accomplishment. This experience does not indicate sagehood. This does not mean you have attained something or have realized sagehood. Do not "mistake a thief for your son."

But if he considers himself a sage, then a demon of memory will enter his mind. Did you hear that! This is truly dangerous! If you consider it a fine state, a demon of memory will come and help you remember things. So you can;t remember something? It will help you to think. It sees how much you would like to remember, so it comes to help you and enters into your mind. Day and night it will hold his mind suspended in one place. Your mind will be preoccupied and kept in one spot. Lacking proper samadhi, unable to attain samadhi, he will certainly fall into the hells in the future
