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.
