Imagination is the mightiest despot

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

Books make men alone for themselves.

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

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.

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