Gratitude is a soil on which joy thrives

Only what thou art in thyself determines thy value, not what thou hast.

Books make men alone for themselves.

Perfect solitude is when, for a whole day, no human eye has beheld your face.

Being alone when one’s belief is firm, is not to be alone.

He who possesses a firm faith, although in solitude, is not alone.

It lies in our own power to attune the mind to cheerfulness.
