“When you fold hands, you neutralize yourself energywise, and when you bow, your whole blood circulation goes toward the head. When the magnetic field is neutral and the circulation goes to the head, the brain functions very well, even the dullest brain starts, becomes bright and active; that’s why in India, it was a custom that when you went to meet your great master or guru or beloved yogi, it was customary to bow to him and it was customary until he tapped on your back that you did not lift your head. What the great gurus used to do was when somebody came and bowed to them, they would take a friend and go on a long walk, and come back after six hours. If the person was still there, they would come and tap his back. They would say, “How are you?” He would say, “I am enlightened.” Naturally, six hours, six hours in that position could enlighten a dead person.” Yogi Bhajan
