(Srila Prabhupada in Tompkins Square Park, New York City, 1966)
"We have no business. We know the Supreme, and the Supreme knows what I want. So I haven't got to ask even the Supreme that 'This thing I want.' No, there is no need. He knows. He will supply because I am engaged in His business. What is our business? Why we are bothering so much in this old age? The only business is that people may know Kṛṣṇa, the supreme controller. That is our business. We have no other business. We don't want anything, either from Kṛṣṇa or from demigod or anyone. Our only business is, as advised by Caitanya Mahā... Yāre dekha, tāre kaha kṛṣṇa-upadeśa (CC Madhya 7.128). This is our business. We are carrying this Bhagavad-gītā as it is, and we are trying to educate people that 'Here is real knowledge. Take it.' This is our business. That means Kṛṣṇa is the Supreme. Īśvaraḥ param... That is our only business. That is our only ambition, that people may know that Kṛṣṇa the Supreme Lord, that's all. We have no other business.
So for that purpose Kṛṣṇa wants. Therefore He comes. He teaches Bhagavad-gītā, that He is the Supreme. Mattaḥ parataraṁ nānyat kiñcid asti dhan... (BG 7.7). He wants to... Ahaṁ sarvasya prabhavaḥ (BG 10.8). He wants to spread this knowledge. We are spreading the same knowledge. We are helping Kṛṣṇa. Not helping—we are serving Kṛṣṇa. Caitanya Mahāprabhu comes for this mission. Kṛṣṇas tu bhagavān svayam (SB 1.3.28). He preaches. What is Kṛṣṇa and Caitanya Mahāprabhu's mission? He simply preached Kṛṣṇa, 'Chant Hare Kṛṣṇa. Understand Kṛṣṇa.' So our only business is to spread that Kṛṣṇa is the Supreme Lord. So Kṛṣṇa is very, very pleased, that 'What I want to do—I go there, incarnate and spread—that he is doing.' Therefore we are already in the direct service of the Lord, so we have nothing to ask from anybody else. If we ask anything from anybody, that is for his benefit, not for our benefit."
