Once man realizes that every activity and impulse that comes into his mind is really from God, from that time he feels that it must be fulfilled. If it is not fulfilled, it is man's limitation that is the cause of its hindrance; he has allowed his weakness to hinder its accomplishment. It is man's lack of faith that generally causes failures. In faith is the secret of fulfillment or non-fulfillment of every thought. There is no doubt about the fulfillment of a desire if man's faith works with it. But when one's own reason and doubt come and destroy the hope, one generally meets with failure.
