organisms, conscious energy exists in five sheaths (koshas)
and operates through the entire body :
||The sheath of matter
or the cellular body, created by prana out of anna, food.
||The sheath of vital
air or prana, which supports all mental, super-mental
and psychic energy.
||The sheath of Mind,
the mental body, a variety of feelings and emotions generated
by the chemical soup prepared in the Annamayi Kosha.
||The sheath of knowledge
beyond sensory perception, containing the Buddhi (intellect)
and the Ahamkara (the Ego or I-consciousness).
||The sheath of bliss,
containing the chitta or pure being of individualized
consciousness and non-dual cosmic consciousness.
The understanding of indian psychology is essential
to the understanding of the purpose and methods of yoga.
