"Falseness of Hath-Yoga-Dissection of human body"

Swamiji had studied books like Hath-Yog Pradipika, Yog Bijak on Hath Yoga and was very eager to verify the truth about the inside of human body as described in Hath-Yoga books. One day Swamiji saw a human dead body floating in river water. He pulled it out and with the help of sharp knife performed dissection of the body and compared it with the description given in Hath Yoga books. Finding that there was no similarity in the description and the body dissected, Swamiji made pieces of pages of the books on Hath-Yoga and made them flow in river with the dissected body. He was convinced of the falsehood of Hath-Yoga system.
