The Kṛṣṇa name is so powerful transcendentally, spiritually, that if you chant once "Kṛṣṇa," all your sinful activities, reaction, are immediately finished. One may say that, "He was not so sinful. He was little sinful; therefore it is finished." But this verse says that the vibration of "Kṛṣṇa," this sound, has so much potency that it can finish the reaction of all sinful activities as you cannot perform in your various lives. Even if you are very expert in committing sinful activities, still, this will finish, provided it is chanted offenselessly. It has got the power.
So if we always chant . . . suppose I am now freed from all sinful reaction. I may be attacked again. That is quite possible. I may be free from the disease but I may be attacked again by this disease. That is possible. But if you always keep yourself constantly in Kṛṣṇa consciousness, chanting Hare Kṛṣṇa—therefore we supply the beads and ask the student, "Chant Hare Kṛṣṇa"—then sinful activities cannot touch you. These are the processes. And if you keep yourself without being touched by the sinful activities, then one who does so achieves liberation in the Supreme. Then your liberation is guaranteed.
Yes.
Revatīnandana: Purport: "Only a person who is fully in Kṛṣṇa consciousness can be said to be engaged in welfare work for all living entities."
Prabhupāda: Yes. For all living entities. You can open a hospital for the human being, but where is your hospital for the tiger? Can any man open a hospital for the tigers, for the snakes? And why not? You are compassionate with living entities. Are they not living entities? This is the frailty of imperfect knowledge. They are giving protection . . . the state is giving protection to the national, but the cows are not national; they should be killed. But the definition of national is that one who is born in that land is called national. Are the cows are not born in this land? Why for them killing, and only for the human being protection? This is imperfect, imperfect knowledge.
So whatever a man is doing, you will find some imperfectness. But this Kṛṣṇa consciousness movement is so nice that it has no imperfectness. It is all-perfect. It is for all living entities, not that I shall simply give protection to my brother, my sister or my father, but even to the lowest animal we shall give protection. This is Kṛṣṇa consciousness.
Therefore, "Only a person who is fully in Kṛṣṇa consciousness can be said to be engaged in welfare work for all living entities." Why discrimination? Why protect this and not that? That is imperfectness. The human society cannot give protection to all living entities, but here is a scheme which can give protection to all living entities.
