Svarūpa Dāmodara: The original substance that I started with, changed to some other form.
Prabhupāda: Yes. It is just like you take cotton. You make thread. Another form. Then from thread, you make cotton cloth.
Brahmānanda: It's not lost.
Prabhupāda: It is not lost.
Brahmānanda: It just changes it's form.
Prabhupāda: The original cotton is there. Simply form is changing. This is the process.
Svarūpa Dāmodara: Is it the same from pūrṇasya pūrṇam ādāya... (Iso Invocation)?
Prabhupāda: Yes. Everything is preserved. Kārya kāraṇam, cause and effect. In the effect, the cause is there. Therefore, Veda says: sarvaṁ khalv idaṁ brahma, everything is Brahman. Because the cosmic manifestation is the effect of the cause, energy of God. Therefore, in the effect there is God. mayā tatam idaṁ sarvaṁ jagad avyakta-mūrtinā. "In impersonal form, I am existing everywhere." God says, Kṛṣṇa says. Mat-sthāni sarva-bhūtāni (BG 9.4). "Everything is existing on Me." Na cāhaṁ teṣu ava... "But I am not there." This is the personal and impersonal features of the Lord.
