Bob: Lord Caitanya, He was a different type of guru than you were?
Prabhupāda: No, no. Guru cannot be different types. All gurus are of one type.
Bob: But He was, was He also an incarnation at the same...?
Prabhupāda: Yes, He is Kṛṣṇa Himself, but He is representing as guru.
Bob: I see.
Prabhupāda: Yes.
Bob: And then.
Prabhupāda: Because Kṛṣṇa, as God, He demanded that sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). But people misunderstood Him. Therefore Kṛṣṇa again came as guru and taught people how to surrender to Kṛṣṇa.
