Human civilization is responsible life. Actually, we are being educated, we go to school, to college, to become responsible man. So this responsibility should be, "How to stop this repetition of birth." In many places this is advised. And that is the only aim of human life. Punar-janma-jayāya. I have told you many times that when Viśvāmitra Muni went to Daśaratha Mahārāja to take Rāmacandra and Lakṣmaṇa to kill one demon in the forest . . . Viśvāmitra Muni is brāhmaṇa. He was so powerful, he could himself kill that demon, but because he is brāhmaṇa, he is not allowed to kill. A brāhmaṇa must be nonviolent. So therefore he went to the kṣatriya, Mahārāja Daśaratha. This is kṣatriya's business. Kṣatriya means . . . kṣat means injury, and tra means deliver. The kṣatriya's duty is . . . there is somebody is creating disturbance, injury to others, it is the government's duty, kṣatriya's duty, to punish him immediately, or, if required, to kill him, immediately. That is kṣatriya's duty.
So one demon was very much disturbing the ṛṣis in the jungle. So they came to Daśaratha Mahārāja to get some relief. Kṣatraṁ dvijatvaṁ ca parasparārtham. He said, "My dear King Daśaratha, I have come to you for some help. The disturbance is going on." Just like we go to the government for police help if there is some disturbance; this is the duty of the government, kṣatriya. So "We are having sacrifices, penances for the whole humanity. Now we are disturbed. You save us." Kṣatraṁ dvijatvaṁ ca parasparārtham. This is required. Parasparārtham means mutual help. The brāhmaṇas should give advice to the kṣatriyas, to the government, and the government, according to the nice, good advice, should maintain the state. In this way there will be peaceful condition of the society. Therefore there is the institution of varṇāśrama.
