Sincerity is the foundation of the spiritual life.

Train yourself never to put off the word or action for the expression of gratitude.

Good is that which promotes life, evil is that which destroys life

The great fault of all ethics hitherto has been that they believed themselves to have to deal only with the relations of man to man. In reality, however, the question is what is his attitude to the world and all life that comes within his reach.

I see in him (Dr. Max Gerson) one of the most eminent medical geniuses in the history of medicine...he was greatly impeded by adverse political conditions.

The mistake made by all previous systems of ethics has been the failure to recognize that life as such is the mysterious value with which they have to deal. All spiritual life meets us within natural life. Reverence for life, therefore, is applied to natural life and spiritual life alike. In the parable of Jesus, the shepherd saves not merely the soul of the lost sheep but the whole animal. The stronger the reverence for natural life, the stronger grows also that for spiritual life.

Because I have confidence in the power of truth, and of the spirit, I have confidence in the future of mankind.
