The children, they are dancing, they are chanting, they are playing the cymbal. All these activities are taking into account. Krta-punya-punjah. We collect all these effects of pious activities. This devotional service is so nice that whatever you do, little bit, that is pious. Punya-sravana-kirtanah [SB 1.2.17].

Even if you do not do anything, simply if you hear, that is also punya. Punya-sravana-kirtanah. And if I speak just like a parrot, if I do not know anything about, it doesn’t matter; still, it is pious.

Punya-sravana-kirtanah. Someway or other… The children, what do they know about Krsna consciousness? But they are becoming pious, purified. This little, little accumulation of punya, very easy. No expenditure, no experience, no education, nothing. Simply come here and join this chanting and dancing. Even a child. Krta-punya-punjah. Little, little, little — one day he will be able to play with Krsna.
