Astral-body.
The word “astral-body” comes from Plato’s philosophy, and while it does relate to the astral-plane, it should not be confused with the Etheric-double (which is a separate energy-body).
(The Astral-body is not really blue, but I wanted to illustrate the fact that it’s a higher frequency than the Etheric-double).
The Astral-body is approximately the shape of the human body (although slightly larger), and is connected to the other body-systems via a thin, flexible-length energy-line to the belly area.
That connection at the belly area extends downward, inside the body, to a complex structure in the lower belly.
When the meat-body is asleep (or “daydreaming”), the astral-body will move away from it (usually upwards), and drift around during dreaming, but a sudden unexpected sound can often cause it to snap back into the meat-body position, which can be experienced as a slight shock. This phenomena of Astral-body leaving and snapping-back also often happens during meditation.
When in good condition the astral-body is very playful and curious. This can be seen in the behavior of dolphins and whales who have a lot of awareness in their Astral-body.
Most ghosts are Astral-body’s which have persisted after the death of the meat-body (which can be used as something for the Ultimate-self (if there is one present) to hold on to), often due to trauma which the being is unwilling to face yet.
Astral-body is mainly involved with creativity in the Magick-universe aesthetic ranges. Those creations influence Etheric-double, forming the majority of emotions (if it is in less than ideal condition) there.
Since an Astral-body was originally designed to be a vehicle for an Ultimate-self, it contains a Terminal-structure. When used in a living human body, this Terminal-structure is empty, but when the meat and bones body dies and an Ultimate-self uses Astral-body as its vehicle, the Terminal of that Astral-body becomes active and contains data.
The set of 7 chakras below the feet pertain to the Astral-body.
