The witnessing soul is like the sky. The birds fly in the sky but they don't leave any footprints. That's what Buddha says that the man who is awakened lives in such a way that he leaves no footprints. He never looks ahead, he never looks back, he lives in the moment. Ours is but to do the task that falls to our lot.
Self confidence is that which remains unshaken even amidst disappointment.
If I have faith in truth and non violence, I will stick to them even in adversity. We acquire certain habits and then we are unable to do anything different. Thought is the father of the action. So guard your deeds and thoughts because when thought goes, action automatically goes with it. It is our duty to keep it under control.
