These sadhanas are not new and have been practiced or
performed since time immemorial by our great sages and
Rishis as well as by incarnates like Mahavir and Gautam
Buddha , who later developed their owns systems which are
still practiced by the Jain monies and the Buddhist monks.
The great sages practiced it in the past with certain
changes to suit the time and space then. It is said and
mentioned in the scriptures (Ravan Sanhita ) that Ravana was
the master in all these VAidhyas .
