know the science of Krishna

So there is no bar for anyone, that one cannot become the spiritual master. Everyone can become spiritual master, provided he knows the science of Krsna. That is the only qualification. And that is very reasonable. If you do not this, do not know the subject matter, how can you be a teacher? Eh? A teacher means he knows the thing. He knows the science. So only qualification of the spiritual master, as Sri Caitanya Mahaprabhu says, kiba sudra, kiba vipra, nyasi kene naya, yei krsna-tattva-vetta: "Anyone who knows the science of Krsna..." This is the science of Krsna, this Bhagavad-gita. If anyone knows perfectly, then he becomes the spiritual master.    (More...)

Prabhupada: If you want to learn something, so you must learn from a person who knows that something. The spiritual master's business is that he knows Krsna well. So you try to understand Krsna through him. This is the idea. Yes?    (More...)
