Premanand Maharaj Ji
What should I do when I doubt myself and fear I cannot fulfil my responsibilities or succeed?
Doubt yourself, never Bhagwan
Take shelter at Bhagwan's feet and keep Him in front of you and behind you, because He is all-capable. Trust in Bhagwan means victory; walk honestly and truthfully.
Walk with honesty and truthfulness and trust Bhagwan; He is the one who grants all capability.
