“When someone has a goal in life, whatever he does to attain it is moral. If you have no goal, whatever you do is immoral.”
This is one of the many teachings of Swami Prajnanpad, an hindu spiritual master who lived in the 20° century. He tried to reconcile science and tradition, materialism and spirituality. He insisted on experimenting, on rejecting any authority. Totally unknown while alive, he wrote no book, giving only advices, teachings to some disciples.
