You may call the Vedas Hindu, but "Hindu" is a foreign name. We are not Hindus. Our real identification is varṇāśrama. Varṇāśrama denotes the followers of the Vedas, those who accept the human society in eight divisions of varṇa and āśrama. There are four divisions of society and four divisions of spiritual life. This is called varṇāśrama. It is stated in the Bhagavad-gītā (4.13), "These divisions are everywhere because they are created by God." The divisions of society are brāhmaṇa, kṣatriya, vaiśya, śūdra. Brāhmaṇa refers to the very intelligent class of men, those who know what is Brahman. Similarly, the kṣatriyas, the administrator group, are the next intelligent class of men. Then the vaiśyas, the mercantile group. These natural classifications are found everywhere. This is the Vedic principle, and we accept it. Vedic principles are accepted as axiomatic truth, for there cannot be any mistake. That is acceptance. For instance, in India cow dung is accepted as pure, and yet cow dung is the stool of an animal. In one place you'll find the Vedic injunction that if you touch stool, you have to take a bath immediately. But in another place it is said that the stool of a cow is pure. If you smear cow dung in an impure place, that place becomes pure. With our ordinary sense we can argue, "This is contradictory." Actually, it is contradictory from the ordinary point of view, but it is not false. It is fact. In Calcutta, a very prominent scientist and doctor analyzed cow dung and found that it contains all antiseptic properties.
In India if one person tells another, "You must do this," the other party may say, "What do you mean? Is this a Vedic injunction, that I have to follow you without any argument?" Vedic injunctions cannot be interpreted. But ultimately, if you carefully study why these injunctions are there, you will find that they are all correct.
The Vedas are not compilations of human knowledge. Vedic knowledge comes from the spiritual world, from Lord Kṛṣṇa. Another name for the Vedas is śruti. Śruti refers to that knowledge which is acquired by hearing. It is not experimental knowledge. Śruti is considered to be like a mother. We take so much knowledge from our mother. For example, if you want to know who your father is, who can answer you? Your mother. If the mother says, "Here is your father," you have to accept it. It is not possible to experiment to find out whether he is your father. Similarly, if you want to know something beyond your experience, beyond your experimental knowledge, beyond the activities of the senses, then you have to accept the Vedas. There is no question of experimenting. It has already been experimented. It is already settled. The version of the mother, for instance, has to be accepted as truth. There is no other way.
