Reverence for life affords me my fundamental principle of morality.
Ethical existence [is] the highest manifestation of spirituality.
Ethics is the activity of man directed to secure the inner perfection of his own personality.
Sincerity is the foundation of the spiritual life.
Living truth is that alone which has its origins in thinking. Just as a tree bears year after year the same fruit which is each year new, so must all permanently valuable ideas be continually born again in thought.
At times our own light goes out and is rekindled by a spark from another person. Each of us has cause to think with deep gratitude of those who have lighted the flame within us.
