Yadubara: Śrīla Prabhupāda. At the time of sleeping, there is a subtle reality that the subtle body enters into?
Prabhupāda: Yes. Reality means as you take this awakening vision as reality, similarly, the dream vision is also real.... Nothing, none of them are reality. They are all temporary.
Yadubara: But that subtle reality is just as real as this gross reality?
Prabhupāda: Yes. They'll not stay. This reality will not stay.
Hari-śauri: It's all a dreamlike existence.
Prabhupāda: Yes, simply a long duration dream. Do you think this skyscraper building will stay? Nothing will stay. It may stay for five hundred years or five thousand years. But is it not permanent. Anything you take—the trees, this land, nothing; even this ocean. Bhūtvā bhūtvā pralīyate (BG 8.19). It appears again and again disappears, that's all. Everything. The material world means that. Bhūtvā bhūtvā pralīyate. Vyaktāvyaktam. Sometimes manifested, sometimes not manifested. This town is manifested, and one big wave of sea, it will be nonmanifested, immediately.
Yadubara: So that subtle reality is existing side by side with this gross reality.
Prabhupāda: Reality is in the spiritual world. This is imitation reality. Real reality is in the spiritual world.
Hari-śauri: We have to go left here, Śrīla Prabhupāda. (pause) The material universes are like a produce of Mahā-Viṣṇu.
Prabhupāda: A big dream, that's all. Material existence means a big dream. How long you'll dream? So long you are in this body. And as long as the body is finished, your dream is finished. Your nation, your society, your friends, your money, your bank, everything finished. Is it not a dream? Then dream another—you become cats and dogs or demigods. You dream in a different way. You are now dreaming as American; next life you may dream something else.
