Nobody ever fails in Yoga....It is slow in the beginning and rapid in the end. When one is fully matured, realization is explosive.
In the mirror of your mind all kinds of pictures appear and disappear. Knowing that they are entirely your own creations, watch them silently come and go. Be alert, but not perturbed. This attitude of silent observation is the very foundation of yoga. You see the picture, but you are not the picture.
What kind of Yoga do you want to practice, the Yoga of getting or the Yoga of giving?... One enslaves, the other liberates.
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.
The attitude of silent observation is the very foundation of yoga. You see the picture, but you are not the picture.
