Everybody does the same mistake: refusing the means, but wanting the ends. You want peace and harmony in the world, but refuse to have them in yourself.
The essence of saintliness is total acceptance of the present moment, harmony with things as they happen.
Live your life without hurting anybody. Harmlessness is a most powerful form of Yoga and it will take you speedily to your goal. This is what I call nisarga yoga, the Natural yoga. It is the art of living in peace and harmony, in friendliness and love. The fruit of it is happiness, uncaused and endless.
If you want peace and harmony in the world, you must have peace and harmony in your hearts and minds.
