If we become pure devotee of Krsna, then my love will be extended to everyone. Not only my society, but to everyone. It is not that "This is my children; that is other's children." All children. All human being. Not my countrymen — all other countrymen. Not only human being, but even animals also. That is sneha. It is not that "I am safe, and let the animals be killed in the slaughterhouse." No, that is not love. Love means for everyone. Samah sarvesu bhutesu. Equality to all living entities. That is real love. That is real concern, Krsna consciousness. A lover of Krsna will hesitate to kill even one ant. You know the story, Mrgari. That is love.

Just like this child. If I like I can kill him, there is no difficulty. But does it mean that I shall kill him? No. Similarly a small ant, anyone can kill. No. Here is a living entity, part and parcel of Krsna, samah sarvesu — he should not be unnecessarily killed. We should be careful, not that "Trample over the ants and let them be killed." No. Everything should be carefully done. Of course, we cannot stop this, but we should be careful, and if it is done, then if we remain Krsna conscious, Krsna will excuse. Yajnarthe karmano 'nyatra [Bg. 3.9].

Therefore the business should be, if we walk at all, we shall walk for Krsna. Then if some ant is killed — not knowingly; unknowingly — then we are untouched by these sinful activities. Otherwise, we are immediately noted down, "Here is a man has killed one, he has…" The nature's law is so minute. Every minute, the account is stepped[?]. But if you remain in the business of Krsna consciousness, then there is excuse. Otherwise, everyone is becoming obliged. If I take from you one cent, I have to pay you with four cent, with interest, compound interest. This is the law. We are… Just like taking money from others. Unless we spend it for Krsna, then we shall be obliged to return again.
