Nabha

“You may control a mad elephant;
You may shut the mouth of the bear and the tiger;
Ride the lion and play with the cobra;
By alchemy you may learn your livelihood;
You may wander through the universe incognito;
Make vassals of the gods; be ever youthful;
You may walk in water and live in fire;
But control of the mind is better and more difficult.”
― Paramahansa Yogananda, Autobiography of a Yogi
