General people understand that retiring from ordinary duties, one becomes spiritually advanced… It is not like that. Krsna taught to the whole world that Arjuna was a soldier, he was a fighter, and in his fighting also he can be Krsna conscious. It is not that he has to cease from fighting and then become Krsna conscious. No. There is no such question. There is no rejection of anything, but dovetailing everything. That is the process. Do everything, but in Krsna consciousness. If you are a fighter, fight, but for Krsna. If you are a businessman, all right. Do business for Krsna. If you are something else, do that, but for Krsna. This is wanted. This is called Krsna consciousness. To dovetail everything with Krsna.

…You can begin Krsna consciousness from the very beginning. Earn for Krsna, spend for Krsna, think for Krsna, work for Krsna. That is Krsna consciousness. Fight for Krsna. Nothing to be rejected. Everything to be dovetailed with Krsna. That is Krsna consciousness.
