There are three stages: jāgarti, svapna, suṣupti. Anyone has got this experience. One stage is that you are awakened, another stage is sleeping, and another stage is unconscious. Jāgarti, svapna and suṣupti, the Sanskrit name. Jāgarti, when you are awakened, our consciousness is very acute, very strong. In sleeping stage, there is consciousness, but it is not so active. And unconscious stage means consciousness is some way or other subdued, not working. Three stages. So death means that unconsciousness for a long period. That is death. Because the soul is eternal. It will be explained. There is no birth and death. So when this body is annihilated, so the soul remains unconscious for a period, seven months for a human being. Seven months unconscious stage within the womb of the mother. After seven months, the consciousness revives. Just like if you have got an experience under chloroform, unconsciousness. The surgical operation takes place, you do not understand, you do not perceive pains and pleasure, but you remains for a certain hours unconscious. Then, gradually, dream comes. Just, from unconsciousness the dream comes. And from dream, you are awakened. As you go down from awakening stage to dream, dream to unconsciousness, similarly, you come up also, from unconsciousness to dream, from dream to awakening conscious stage.
So death means when this body is lost, gross body, the soul remains in the subtle body—intelligence, mind and ego. That subtle body carries him to another body. But those who are not intelligent, they do not understand what is the subtle body, although it is clearly said subtle body means mind, intelligence. You have got mind, intelligence, everyone knows. But these rascals, because they cannot see mind and intelligence, they think that this man is gone, dead. Mind, intelligence, everyone knows that he has got mind. I know you have got your mind, I have got my mind, you have got intelligence, I have got intelligence. But I do not see your intelligence; it is subtle. Just like there is sky, but here is sky in my front, but I do not see. The things, as they become more subtle and subtler, these gross senses cannot experience. Therefore, the soul is so subtle that it is not possible to perceive the presence of soul with these material senses. So these rascals, they simply say, "No, I cannot see soul." How can you see? That is not possible? It is so minute and so subtle that it cannot be seen by this gross eye. Acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet.
