The
etheric body,
ether-body,
æther body, a name given by
neo-Theosophy to a
vital body or
subtle body propounded in
esoteric philosophies as the first or lowest layer in the "human energy field" or
aura.[SUP]
[1][/SUP] It is said to be in immediate contact with the
physical body, to sustain it and connect it with "higher" bodies.
In
physics, a
physical body or
physical object (sometimes simply called a
body or
object) is a collection of
matter with some common attributes, most important, the
spatial location. Examples of
models of physical bodies include, but are not limited to a
particle, several
interacting smaller bodies (particles or other), and
continuous media.
The
astral body is a
subtle body posited by many philosophers, intermediate between the intelligent soul and the physical body, composed of a subtle material.[SUP]
[1][/SUP] The concept ultimately derives from the philosophy of
Plato: it is related to an
astral plane, which consists of the
planetary heavens of astrology. The term was adopted by nineteenth-century
Theosophists and
neo-Rosicrucians.
Mental or
psyche energy or
activity is the concept of a principle of activity powering the operation of the
mind or
psyche. Many modern psychologists or neuroscientists would equate it with increased metabolism in neurons of the brain.
