Prabhupada Vani.....

"One who has cultured himself that these different activities of the material world have nothing to do with him, his only business is to become Krsna conscious. Then it is to be understood that he has conquered death even in this present life. This sort of equilibrium in the transcendental stage of Krsna consciousness is called faultless. It is faultless life."
