COW DUNG - PURE AND ANTICEPTIC

"The whole Vedic knowledge is infallible. There are different examples how we take Vedic knowledge as infallible. Take for example, so far the Hindus are concerned, and how they accept the Vedic knowledge as complete, here is an example. Just like the cow dung. The cow dung is the stool of an animal.

According to smṛti or Vedic wisdom, if one touches the stool of an animal he has to take bath to purify himself. But in the Vedic scriptures the cow dung is stated as pure. Rather, impure place or impure things are purified by touch of the cow dung. 

Now if one argues how it is that in one place it is said that the stool of the animal is impure and another place it is said that the cow dung which is also the stool of an animal, it is pure, so it is contradictory. It may appear to be contradictory, but because it is Vedic injunction, therefore for our practical purposes we accept it. And by that acceptance we are not committing any mistake. 

It has been found by modern chemists, modern science, one Dr. Lal Mohan Gosal, he has very minutely analyzed the cow dung and he has found that cow dung is a composition of all antiseptic properties.

So my idea is that Vedic knowledge is complete because it is above all doubts and all mistakes. Bhagavad-gītā is the essence of all Vedic knowledge. The Vedic knowledge is therefore infallible. It comes down through the perfect disciplic succession."
