Those who are conducting this movement, they must be very well-behaved. Nobody can find out any fault. That is susilah. The behavior should be so nice. That is the test of how you have become Krsna conscious. That is the test. Spotless … Sadhu. A saintly person is friend to everyone. He does not create an enemy but these demons, rascals, out of their envy they become our enemy. Otherwise our process is not to make an enemy. We invite everyone, ‘Please come here, take prasadam, chant Hare Krsna, dance and go home.’ Where is enmity? But still they’ll become enemy. That is the world. But if he lives with the sadhavah, susilah, and follows the rule and regulations, then he also becomes sadhavah. So the Krsna consciousness movement is simply giving chance to people without discrimination, ‘Please come. Become narayana-parayana, devotee, and automatically you’ll become susilah and sadhu.’ Therefore this path is the best way of advancing in our life and go back home, back to Godhead.
