Sad-vaiṣṇavaḥ śva-paco guruḥ. But he is śva-paca. Śva-paca means dog-eaters. They are considered to be lowest of the mankind, dog-eaters. There are different types of eaters—cow-eaters, goat-eaters and camel-eaters, this eater, that eater. There are so many. Out of that eaters, one who eats the dog, he is considered the lowest. So even a person coming from the family of dog-eaters, if he knows who is God, he can be guru. This is the . . . this is the injunction of the śāstra. One who knows God, he cannot remain dog-eaters. But sometimes he comes from there, so . . . but śāstra says: "Yes. When he has learned the science of God, then he can be accepted as guru." That is the confirmation of Caitanya Mahāprabhu:
- kibā vipra, kibā śūdra, nyāsīya
- yei kåñëa-tattva-vettä sei 'guru' haya
- (CC Madhya 8.128)
Who can become guru? Anyone who knows the science of Kṛṣṇa, he can become guru. That is the injunction. Yei . . . it doesn't matter. Kibā vipra kibā śūdra, nyāsī kene naya. He may be a brāhmaṇa, he may be a śūdra, he may be a sannyāsī, he may be a gṛhastha. It doesn't matter. He may be European, he may be American, he may be Indian. It doesn't matter. If he knows the science, yei kṛṣṇa-tattva-vettā sei guru haya (CC Madhya 8.128). So it is not limited under certain country, certain atmosphere or certain population. Kṛṣṇa consciousness is open for everyone. So therefore our request is that these Europeans and Americans who have taken to Kṛṣṇa consciousness just become perfect in the understanding of this science and become guru and deliver the whole world.
