The story says Indra, the King of gods, came to him and said to Mahavir, "I can defend you. It has become so painful. You are being beaten unnecessarily, so just allow me to defend you."
Mahavir rejected the help. Later on, when he was asked why he rejected the help, he said, "This path of will is a lonely path. You cannot even have a helper with you because then the struggle loosens. Then the struggle becomes partial. Then you can depend on someone else, and wherever there is dependence sleep comes in. One has to be totally independent; only then can one be awake.
This is one path, one basic attitude. All these methods of witnessing belong to this path. So when I say, "Be a witness." it is meant for those who are travellers on the path of will.
