Prabhupada, Melbourne, June 29, 1974: [….] By Krishna’s mercy one gets guru, and guru’s mercy one gets Krishna. So, if one is sincere, he will take advantage of guru’s mercy and Krishna’s mercy, and then he will be perfect. This is called bhakti-yoga.

Not that, “I am now very much advanced, I don’t require any help from my guru”, as somebody are doing. This is rascaldom. You cannot get Krishna by overcoming guru. That is not possible. Therefore Caitanya-caritamrita, guru-krsna-krpaya paya. We should always remember that by the mercy of Krishna we get guru, and by the mercy of guru we get Krishna.

So we have to seek mercies of both of them.
So, mayy asakta, mad, mad-asrayah. Mad-asrayah means, mat-asrayah, one…., guru means…., who has taken full shelter of Krishna, he is guru. A, a guru does not mean that he has taken shelter of somebody else and he has become guru. That is not. Guru means one who has taken full shelter, complete surrender to Krishna, he is guru. Or he speaks only what is spoken by Krishna. Just like we have, speaking in this Bhagavad-gita, as it is. There is no malinterpretation. Full Lecture
