Sathya Sai Speaks-Volume I

To a worldly man, a God-intoxicated person will appear mad
and he will laugh at him for it. But to the God-intoxicated man, the
worldly appear insane, foolish misled, blind. Of all the insanities that
harass man, God-madness is the least harmful, the most beneficial.
The world has suffered untold damage due to its "mad" rulers and
"mad" guides; but nothing but harmony, peace, brotherliness and
love have come out of the 'God-madness' of man!

Prashaanthi Nilayam, Mahaashivaraathri, 1955
