Courage is the tonic for getting both physical as well as mental health and strength. Give up doubt, hesitation and fear. Man by means of the inner divine strength with which he is equipped, can achieve anything. The chief source of bliss is dedication to God; nothing else can give the genuine and lasting joy.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
