A fasting person is in a state of worship even if asleep in bed. Every breath he takes while asleep is ‘tasbih’, and his sleep itself is worship.
This is peace, this is excellent, namely the calm of all impulses, the casting out of all “basis”, the extinction of craving, dispassion, stopping-nirvana.
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.
Do not race after riches, do not risk your life for success, or you will let slip the heaven within you.
