The pure mystic wishes to approach his God only in the all-embracing love. The yogi, too, walks toward one single aspect of God. The bhakti-yogi keeps to the road of love and devotion, the raja and hatha yogi choose the path of self-control or volition, the jnana yogi will follow that of wisdom and cognition.
Franz BardonThe activities and effects of the Fire and Air elements in the astral sphere call forth the astral-electric fluid, and the activities and effects of the Water and Earth elements call forth the astral-magnetic fluid. The spirit-beings use these fluids to create the effects or rather the causes in our physical world. The Akasha Principle of the astral sphere maintains the harmonious equilibrium of the elements in the entire astral sphere.
Franz BardonThrough a particular magical practice it is possible to modify the being that has only one element into a being with four elements and to give it an immortal spirit. But a magicial will seldom intervene without good reason, because he is responsible and must justify his actions before Divine Providence.
