The Vedas are considered to be the mother, and Brahma 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 Brahma. He received this Vedic knowledge and imparted it to Narada and other disciples and sons, and they also distributed it to their disciples. In this way, the Vedic knowledge comes down by disciplic succession. It is also confirmed in the Bhagavad-gita 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 the authority, then whatever she says can be accepted without argument. There are three kinds of evidence: pratyaksa, anumana and sabda. Pratyaksa means "direct evidence." Direct evidence is not very good because our senses are not perfect. We are seeing the sun daily, and it appears to us just like a small disc, but it is actually far, far larger than many planets. Of what value is this seeing? Therefore we have to read books; then we can understand about the sun. So direct experience is not perfect. Then there is an anumana, inductive knowledge: "It may be like this"-hypothesis. For instance, Darwin's theory says it may be like this, it may be like that. But that is not science. That is a suggestion, and it is also not perfect. But if you receive the knowledge from the authoritative sources, that is perfect. If you receive a program guide from the radio station authorities, you accept it. You don't deny it; you don't have to make an experiment, because it is received from the authoritative sources.
My Question is like :
>> If you want to know who your father is and if you accept your mother as the authority
How do i know the person is my real/true mother ?
How do you know who is the authority, by direct evidence or inductive evidence, which are both imperfect in the first place?
We are subject to make mistake on selecting/trusting who is authority ??
