Tusk, yes. That is more dangerous. They live in the jungle. And viḍ-varāha means they live in the forest, finding out "Where is stool? Where is stool? Where is stool?" Śva-viḍ-varāha uṣṭra. Uṣṭra means camel, and khara means ass. So here it is a very terse remark, that "Anyone who has never heard the glories of Gadāgraja, the Supreme Personality of Godhead—in other words, one who is not Kṛṣṇa conscious, does not know anything about Kṛṣṇa, or God—they are no better than these animals, especially: dog, hog, ass, camel." Why these four kinds of animals have been selected to compare? That is explained. Śva means dog. A dog, however powerful it may be, very strong, stout, but it, unless it has got a master, its life is very precarious. Dog. Just see our education at the present moment. Very advanced education. Many Indian students come here also to take advanced education. But actually, we consider this education creating dogs. Why? Now, because however technologist you may be, if you don't get a suitable service, all your education is finished.
Therefore, after education you'll have to write application, "My dear sir, I am such and such qualified dog. (laughter) If you'll kindly give me some service." And the tail is like this. (laughter) You see? Just imagine. If by education he becomes independent ... Just like Vedic culture. The brāhmaṇas, the kṣatriya, the vaiśyas, they are independent. The śūdras are compared with the dogs because they cannot live without a master. Brāhmaṇa, he will not accept anyone's service. That is real brāhmaṇa. A kṣatriya will never accept anyone's service. Why the battle of Kurukṣetra was there? The Kurus, they took away the whole kingdom of the Pāṇḍavas. But they were kṣatriyas. How they will live? Therefore the fight was necessity. The kṣatriyas must be, must have some land to collect taxes. That is the kṣatriya's source of income. The brāhmaṇa's source of income, paṭhana pāṭhana yajana yājana ... They must be learned scholar, they must teach others, they must be devotee and teach others how to become devotee.
They must take contribution and must spend for Kṛṣṇa. This is brāhmaṇa. No service. Formerly, no brāhmaṇa ... Sanātana Gosvāmī, Rūpa Gosvāmī, they were born in high-class brāhmaṇa family, Sārasvata brāhmaṇa, but because they accepted the service of Nawab Hussein Shah, immediately they were rejected from brāhmaṇa society. It is by the grace of Caitanya Mahāprabhu that they again became gosvāmī. Otherwise, they were rejected. No brāhmaṇa could take service and especially service of a low-class man. That is ... In Bhāgavata you will see especially that if a brāhmaṇa is in difficulty, he may accept the profession of a kṣatriya or utmost of a vaiśya, but never take the profession of a śūdra. What is the profession of śūdra? Śūdra ... Paricaryātmakaṁ kāryaṁ śūdra-karma śvabhāva-jam (BG 18.44). One who is hankering after service, he is śūdra. He has no capacity to live independently. The brāhmaṇa, real brāhmaṇa, he will starve, he will die out of starvation.
