The astral plane, the seat of which is the heart, which is situated in the midst of the body and the soul, can only be controlled by a strong love or devotion. Just as the horse is controlled by the will of the driver, in the same way a man whose will controls both driver and horse can hold the rein over his action, speech, thought and feeling. The mind is prone to different temptations and, uncontrolled, it wanders about like a wild horse in a jungle. The will produces an object of love and directs the heart to follow the right path, the path of love, along which one journeys resisting all temptations met with on the way.
