1975 Conversations and Morning Walks

That is here, in this material world. In the spiritual world Kṛṣṇa does not leave. And even in the material world, Kṛṣṇa superficially has gone to Mathurā, but He has captured the heart of the gopīs. So He is not leaving. Gopīs are enjoying Kṛṣṇa by separation.

Morning Walk -- July 17, 1975, San Francisco:

Devotee: This Guru Maharaji claims to be God, but he had to go to childbirth class to learn how to have one child.

Prabhupāda: You should not talk about him, these rascals. Na tasya kāryam kāraṇam ca vidyate, na tasya samaḥ adhikaś ca dṛśyate. This is the definition of God, that he has nothing to do personally. When Kṛṣṇa kills the demons outside Vṛndāvana, He is not original Kṛṣṇa; He is Vāsudeva. Vāsudevaḥ sarvam iti (BG 7.19). When Kṛṣṇa is acting universally, that is Vāsudeva. Original Kṛṣṇa is always in Vṛndāvana.

Jayatīrtha: If the original Kṛṣṇa is always in Vṛndāvana, then why do the gopīs and Rādhārāṇī feel separation from Him?

Prabhupāda: That is here, in this material world. In the spiritual world Kṛṣṇa does not leave.

Jayatīrtha: Oh.

Prabhupāda: And even in the material world, Kṛṣṇa superficially has gone to Mathurā, but He has captured the heart of the gopīs. So He is not leaving. Gopīs are enjoying Kṛṣṇa by separation. That is Caitanya Mahāprabhu's feeling, how He is appreciating Kṛṣṇa by separation.
