Bob: Lord Caitanya, He was not a guru; He was different than guru?
Prabhupāda: He's guru.
Bob: Lord Caitanya, He was a different type of guru than you were?
Prabhupāda: No, 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, I see.
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.
Śyāmasundara: Doesn't He say in the Bhagavad-gītā, "I am the spiritual master"?
Śyāmasundara: Doesn't Kṛṣṇa say: "I am the spiritual master"? In Bhagavad-gītā it says . . .
Prabhupāda: Yes, He's the original spiritual master, because He was accepted spiritual master of Arjuna. So what is the difficulty? Śiṣyas te 'haṁ śādhi māṁ tvāṁ prapannam (BG 2.7). "I am Your disciple." So unless He's spiritual master, how Arjuna becomes His disciple? He's the original guru. Tene brahma hṛdā ādi-kavaye, in the Bhāgavata, that He gave instruction about Vedas in the heart of Brahmā. So He's guru.
