You have to grow from the inside out. None can teach you, none can make you spiritual. There is no other teacher but your own soul.

The trouble isn't so much that our scientific genius lags behind, but our moral genius lags behind. The great problem facing modern man is that, that the means by which we live have outdistanced the spiritual ends for which we live.

The moral philosophy and spiritual conceptions of men and nations should hold their own amid these formidable scientific evolutions...No material progress, even though it takes shapes we cannot now conceive, or however it may expand the faculties of man, can bring comfort to his soul.

In the spiritual realm nothing is indifferent: what is not useful is harmful.

For me, the lame part of the Sixties was the political part, the social part. The real part was the spiritual part.

My job in this life is to give people spiritual ecstasy through music. In my concerts people cry, laugh, dance. If they climaxed spiritually, I did my job. I did it decently and honestly.
