Not unlike our physical sun (the source of all visible light that can be broken up into its seven component colors), the Solar Logos of our system too is a source of seven great cosmic Rays of spiritual light that can help accelerate our spiritual growth. These Rays build up the causal body of man, and to each of them there are various spiritual and physical qualities assigned. In this case we can say that the term "Ray" is used in a sense of one special type of force or energetic quality. These seven great streams of energy represent each and every vibration in nature, space and form, and they permeate all objects, all beings and all events in manifestation. They interpenetrate each other and combine themselves in order to produce more complex systems which we refer to as "reality". The seven Rays surpass the possible description by words, or even by thoughts or feelings. They are too essential and all-encompassing to be limited within our own narrow inner space of perception of the great spectrum of reality. Still, certain description of these Rays is possible in terms of the corresponding qualities. Certain qualities of the Rays can be also connected to the seven chakras and to the crystals and mineral kingdom.
