"So this Kṛṣṇa consciousness movement is trying to give Kṛṣṇa. Kṛṣṇa se tomāra, kṛṣṇa dite pāra. Bhaktivinoda Ṭhākura has sung that vaiṣṇava ṭhākura, tomāra kukura baliyā jānaha more. He's presenting himself, 'My dear sir, Vaiṣṇava, kindly accept me as your dog.' Kṛṣṇa se tomāra, kṛṣṇa dite pāra, tomāra śakati āche. This is a fact.
If you want Kṛṣṇa, then you have to approach a pure devotee of Kṛṣṇa. He can give you, deliver you. Vedeṣu durlabha adurlabha ātma-bhaktau. If one is Kṛṣṇa devotee, he can deliver Kṛṣṇa: 'Take Him. Here is Kṛṣṇa.' That is the special prerogative of devotee.
Kaunteya pratijānīhi. Kṛṣṇa is advising Arjuna, because he's devotee, that 'You declare, na me bhaktaḥ praṇaśyati.' So He could declare Himself. No. He wants to declare everything through His devotee."
