True friendship can afford true knowledge. It does not depend on darkness and ignorance.

That friendship will not continue to the end which is begun for an end.

No person is your friend who demands your silence, or denies your right to grow.

True friendship ought never to conceal what it thinks.

Friendship with ones self is all important, because without it one cannot be friends with anyone else in the world.

A man's friendships are one of the best measures of his worth.

Friendship is unnecessary, like philosophy, like art... It has no survival value rather it is one of those things that give value to survival.

There is nothing on this earth more to be prized than true friendship.

A true friend is the greatest of all blessings, and that which we take the least care of all to acquire.

A true friend is one who overlooks your failures and tolerates your success!
