It is the duty of an advanced mystic who wishes to attain greater heights for himself and be of greater service to others to try earnestly to graduate to the ultimate path. This does not demand that he give up any of his mystical practices or beliefs, but merely that he amplify and supplement them. He must first develop the trinity of head, heart, and hand, or reason, intuition, and action, and then bring them all into proper balance. If in addition he is inspired by the ideal of service, he will attract to himself the unseen help of those who are also dedicated to such service.
