Devotee: I understand, Śrīla Prabhupāda, that the pure devotee can be as pervasive as Supersoul?
Devotee: By the mercy of Supersoul, he can be present in many places at once?
Prabhupāda: Yes. By the grace of Kṛṣṇa, a devotee can become anything.
Devotee (2): So in other words that means the pure devotees can be omniscient?
Prabhupāda: Everything. God is omniscient, so a pure devotee can become omniscient by the grace of God.
