Only He who made man makes man happy.

The punishment of every disordered mind is its own disorder.

Let those who think I have said too little and those who think I have said too much, forgive me; and let those who think I have said just enough thank God with me.

The mind commands the body and is instantly obeyed. The mind commands itself and meets resistance. The mind commands the hand to move, and it so easy that one hardly distinguishes the order from its execution. Yet mind is mind and hand is body. The mind orders the mind to will. The recipient of the order is itself, yet it does not perform it.

One can't reach the Truth but through Love.
