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  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.
The  Vedas  are considered to be the mother and Brahmā is called the grandfather, the forefather, because he was the first to be instructed in the Vedic knowledge. In the beginning the first living creature was Brahmā. He received this Vedic knowledge and imparted it to Nārada and other disciples and sons, and they also distributed it to their disciples. In this way, the Vedic knowledge comes down by discipline succession. It is also confirmed in the  Bhagavad-gītā , that Vedic knowledge is understood in this way. If you make experimental endeavor, you come to the same conclusion, but just to save time you should accept. If you want to know who your father is and if you accept your mother as authority, then whatever she says can be accepted
