Prabhupāda: That individual is Kṛṣṇa. Kṛṣṇa knows that so many atoms will be combined, then another thing will be formed. It is not the individual soul but Kṛṣṇa directly.
Śyāmasundara: But when you come to the living entities, then the individual soul is also there.
Prabhupāda: Yes. Within the body. Both of them—Kṛṣṇa is also there, and the individual soul is also there.
Śyāmasundara: He says that the definition of substance is a being capable of action. Substance means to be capable of action, and that existence means action.
Prabhupāda: Substance is original. Other things are categories.
