Out of his own heart a man may seek guidance for his future. His former sins become his future teacher. His errors, once perceived, show him the right way. His thoughts, once overcome, provide him with new strength and new virtues. His trials, met and mastered, open new doors of consciousness to him. His weaknesses offer him a challenge and if he takes it up and if he uses his will to transmute them, he will be the gainer.
