Many teachers will tell you to believe; then they put out your eyes of reason and instruct you to follow only their logic. But I want you to keep your eyes of reason open; in addition, I will open in you another eye, the eye of wisdom.
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 earn your livelihood; You may wander through the universe incognito; Make vassals of the gods; be ever youthful; You may walk on water and live in fire; But control of the mind is better and more difficult.
I reached in experience the nirvana which is unborn, unrivalled, secure from attachment, undecaying and unstained. This condition is indeed reached by me - deep, difficult to see, difficult to understand, tranquil, excellent, beyond the reach of mere logic, subtle, and to be realised only by the wise.
