The Seven Planes of Being

This description of the 7 Planes comes from Rick Richards Site (RickRichards.com) 

7. The Material Plane. The Material Plane is the plane in which we live and inhabit and is the lowest of the 7 planes.

6. The Plane of Forces. This is the plane where "Prana" or "Vital Forces" resides. This field is only becoming known today into research of radioactivity.

5. The Astral Plane. The Astral Plane is the realm in which we pass after death for a short period before entering the higher realms of being. It is believed to inhibit not only disembodied beings but also inhabitants of non-human nature, such a devas or angels, or nature spirits.

4. The Mental Plane. This is where the soul has finally completed his or her work, in the Astral Plane. The soul slumps into a astral slumber and blast into the higher plane of existence, this is and experience followed be extreme sensations of flying higher and dizziness, followed by feeling of being lifted out of your physical body, I have experienced this on many occasions.

3.2.1 The Highest Planes for which there is no name are realms of the highest planes. These planes of existence can differ for the individual soul and for the astral traveler, and have no definite description because everyone experiences different.
