In Hindu religion, Sharira means the body, literally, that which is subject to destruction. It has three-fold nature, namely, sthula (gross), Sukshma (subtle) and karana (causal). The gross body is made up of five elements – earth, water, air, fire and ether – and after their pancakarana (grossification), it is subject to the modifications of existence – birth, growth, maturity, decay and death. The subtle body is composed of the five elements before their grossification, which are called tanmatras. It is made up of five karmendriyas (organs of actions), five jnanedriyas (organs of perception), five pranas, manas (mind) and buddhi (intellect). Karana Sharira or the causal body is the ignorance, which is the cause of the other two bodies.
Sthoola/Sookshma sharira can be broadly stated as the
mind-body complex, upadhi (adjunct) that conditions or limits the all-pervasive
consciousness. This conditioning, caused by ignorance, leads to the
superimposition of attributes of the body onto the self and vice versa. Thus
the feeling of being embodied leads to wrong identification of the self with
the body. On the other hand, the knowledge of dis-embodiedness is the absence
of such false self-identification with the body, rather than loss or destruction
of the body. Hence the knowledge of dis-embodiedness is associated with a
realized soul even while living, since avidya (self knowledge) destroys avidya
(non-liberating knowledge) as well as its effect such as false identification.
This is the phenomenon of jivanmukta.
While shariratva (embodiedness) denotes bondage due to the confinement
of the all-pervasive consciousness to a limited mind-body complex, ashariratva
denotes liberation from the false superimposition and the manifestation of the
true nature of the self. The dawn of such discriminatory knowledge leads to the
realization of true self. Thus dis-embodiedness and embodiedness of the self
are the consequences of discriminatory knowledge and its absence, rather than
the result of the presence or absence of the body. As Chandogya Upanishad
states, the bodiless transcends the duality of joy and sorrow, while the
embodied cannot escape the web of alternating sorrows and joys.
