Prabhupāda: And who kept the ocean? You go on.
Svarūpa Dāmodara: By nature.
Prabhupāda: Then you come to somebody. That is foolishness. Then nature is not ultimate. Kṛṣṇa is the ultimate. Because you cannot see Kṛṣṇa, therefore you say, "Nature."
Svarūpa Dāmodara: Kṛṣṇa says, "Nature is under My control."
Prabhupāda: Yes.
Svarūpa Dāmodara: It is just like an equilibrium, Śrīla Prabhupāda. In science it is called equilibrium, means this on and off...
Prabhupāda: It is called cakra. What is that? In Bhagavad-gītā it is said, brahma-cakra, brahma-cakra. Sarvaṁ khalv idaṁ brahma. That is realization, that in every action there is brahman. The beginning, by eating food grains, you become strong. The animals become strong. Then, when you become strong, you perform yajña, and from yajña, there is cloud, and from cloud, there is rain, and from rain, there is food grains. This is the cakra.
