We are all born ignorant, but one must work hard to remain stupid.

Do exactly what you would do if you felt most secure.

One word frees us of all the weight and pain in life. That word is love.

Nature always wears the colors of the spirit.

by means of one person or party: one-sided

The sole meaning of life is to serve humanity.
