Mahāpuruṣa: If the living entity is in the material world and he's an expansion of the marginal energy, then he's... And he can purify himself and become eligible to enter into the spiritual world and Kṛṣṇa, but can he still fall as an expansion of the marginal energy?
Prabhupāda: Yes. Marginal energy. Just like the sunshine is always there. Sometimes it is covered by cloud. When the cloud is cleared, then it is directly touching sunshine. Similarly, we are always marginal potency. Now the māyā cloud has covered me. As soon as māyā is over we are in direct, I am in touch with Kṛṣṇa. We are already in touch with Kṛṣṇa. When the sunshine is covered by the cloud it does not mean that the, there is no sunshine. It has become dim. Similarly, we spirit, individual spirit souls, we are bright. But due to the contact of māyā, we are now not free, not free to exhibit our real life, spiritual life. The whole process is how to get free from the clutches of māyā, then full-fledged spiritual life we get immediately. Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati (BG 18.54).
