So Krsna says... Krsna did not say Bhagavad-gita to the loafer class. Krsna said rajarsi. Arjuna was a rajarsi. So there are... Because king would take responsibility. If the head man is taught very nicely everything about society, economic development and religion, if he is taught very nicely, then he can, I mean to say, introduce the ideas in the country.

Or raja means king and rsi means saintly person. So either the rsis did know or the kings did know. Or a king who is not less than a rsi, he could know and he could rule over.

This is Krsna consciousness movement.    (More...)
