"So for to know Krishna, there are so many Vedic literatures. So we have to know through the mercy of the spiritual master. Tad-vijnanartham sa gurum eva abhigacchet. Everything is there, just like Krishna is there in the Bhagavad-gita, but people could not understand Krishna. Now we are presenting Krishna as it is. People are understanding. They are becoming devotee. So we have to go through the right channel. Then we'll know Krishna. And as soon as you know Krishna as He is, your life is successful. That is the aim and object of Krishna consciousness movement -- simply to help the people to know Krishna. This is the only business, because as soon as you know Krishna, your life is successful in which way, eh? The success is: tyaktva deham punar janma naiti (Bhagavad-gita 4.9). This is success. This body should be the last acceptance of material body. That is success."
(Srila Prabhupada lecture, Mayapur, March 12, 1976)
