Use endorphine with night and day cycles

All spiritual practice including asceticism, self torture, no ego, samadhi, enlightenment, is actually getting endorphin in the brain.

However endorphine in the brain cannot be maintained, there will always be a crash after the high.

But there is a higher level discovered by zen and tao and Kalil Gibran.

Know that there is cycles for all system, night and day always replace eachother. Know that whenever you are unhappy, happiness will be in the corner and come to you. Enjoy both the sessions of happiness and unhappiness. Dont always cling to happiness, unhappiness is a burst of creativity and building.
