A dog is very faithful to his master. He will commit so many offenses for the sake of the master. Because he knows, "The master gives me food." So in your country, if you pass through one's house, from within the house they will bark, "Bark! Bark! Bark! Ba! Ba! Why you are going in front of my house?" This is committing offense, committing offense unnecessarily. So the dog's business: one side, he is very faithful, and one side, he is simply committing offense, unnecessarily frightening other people, you see unnecessarily, without any offense. And dog's another business is that he is seeking always master. Unless he finds out a good master, it is a street dog and it has no place. It has no place. It will not get sufficient food, become lean and thin, and loiter in the street. Because dog must find out... Śūdra-like. Śūdra, unless he finds out a master to provide him, his all education is useless.
Nowadays they are educated, but they must have a good service. That means he's a śūdra. Without finding a master, his education has no value. So therefore in the śāstra it is said, kalau śūdrā sambhavāḥ. Kalau, "In this age, Kali-yuga, everyone is śūdra." Because he cannot even live without having a master. He must have a master to provide him. But the Vedic culture is that brāhmaṇa, kṣatriya, vaiśya, they will not accept any service. No. They will die of starvation. Especially brāhmaṇa.
