Paramahaṁsa: Do people naturally act sinfully, or is that something that they develop?
Prabhupāda: Hm? By association. If you mix with the drunkards, you'll learn how to drink. And if you mix with the devotees, similarly, you can become cleansed. By the association. Saṅgāt sañjāyate kāmaḥ. One's desires develop according to the association.
Bhagavān: Śrīla Prabhupāda, in the Bhagavad-gītā, you state that sometimes they begin to take on these demonic qualities within the womb. These demonic qualities are inherited from the past life. So if we begin Kṛṣṇa conscious education very young, it's possible to stop these demonic qualities from developing?
Prabhupāda: No. His demonic qualities will be purified. Otherwise, what is the use of preaching? If the qualities cannot be changed, then what is the meaning of preaching?
Bhagavān: No, I said if we begin education early, they can be...
Prabhupāda: Yes, as early as possible. From the very womb, you begin education. Let the mother hear about Kṛṣṇa. He'll be purified from the womb. Just like Prahlāda Mahārāja became. He was born by a demon father. But his quality changed when his mother was instructed by Nārada Muni, everything was changed. If the demons cannot be changed, then what is the meaning of preaching?
