Chanakya
There is no enemy can hurt us but by our own hands. Satan could not hurt us, if our own corruption betrayed us not. Afflictions cannot hurt us without our own impatience. Temptations cannot hurt us, without our own yieldance. Death could not hurt us, without the sting of our own sins. Sins could not hurt us, without our own impenitence.
