Greediness is very good. Kamam krsna-karmarpane. Strong desire, that is called lust. So, but this strong desire… Just like gopis. The gopis, they were village girls. They had no understanding of what is God, what is Krsna. But they became very much lusty for Krsna, and Caitanya Mahaprabhu recommended that ramya kacid upasana vrajavadhubir ya kalpita: “There is no better type of worship than what was conceived by the gopis.” Their strong desire, “How we shall get Krsna?” that was their day and night thought. That’s all. Somebody is thinking in some way… The central point was Krsna. I have already explained that, that Krsna was going to the pasturing ground, and the gopis at home, they were thinking that “Krsna’s foot is so soft and so delicate,” and that “We dare not to take His feet on our breast, but He is now walking in the fields, pasturing ground, naked without any… And the stones pricking. How much He is feeling pain.” Thinking this, they became fainted. This is Krsna consciousness. So therefore Caitanya Mahaprabhu recommended ramya kacid upasana. These gopis were not supposed to be educated. Village girls — who is giving them education? They are not Ph.D.’s. But still, strong desire for Krsna. And that is called yesam nirbandhini matih. Nirbandhini, strong desire. It doesn’t require any other price to become advanced in…, simply to become very strongly eager, laulyam. Then life is successful
