(1) The Plane of Matter consists of all experiences in physical form, in matter form, in matter as known to man. These experiences are not confined to the earth life. There are experiences of a similar character in numerous starry regions. Sometimes the body vibrates faster or slower than the body of man in such starry places. But the term “physical” expresses its character and nature.
(2) Hades is a term which corresponds with the astral plane. Immediately on the dissolution of the body there comes a brief period of seeming disintegration, a temporary dislocation of those parts which make you one.
(3) The Plane of Illusion [Summerland] is the dream period connected with life passed on the Plane of Matter.
(4) The Plane of colour. Existence in this state is not governed by the senses. It is more directly controlled by mind. It is still an existence in form, and therefore an existence in substance. That substance is a very rarefied matter. It might be called an air of matter. The Plane of colour is within the terrestrial zone or within the corresponding starry zone wherein the soul previously had experience of a physical existence.
(5) The Plane of Pure Flame. In this state the soul becomes aware of the pattern his spirit is weaving in the tapestry of eternity and realises all the emotional life of those souls fed by the same spirit.
(6) The Plane of Pure Light. Within its borders the soul obtains an intellectual conception of all the previous existences within its group-soul. Further, he realises all emotional life within the body of the world or earth soul.
(7) Lastly, the Seventh Plane [Out Yonder, Timelessness]. The spirit and its various souls are now fused and pass into the Supreme Mind, the Imagination of God, wherein resides the conception of the Whole, of universe after universe, of all states of existence, of past, present and future, of all that has been and all that shall be. Herein is continuous and complete consciousness, the true reality.
