The Linga Sharira, or Long Body, refers to the total or composite body of a man from birth to death as it should be revealed if the time-process in which it is perceived consecutively were to be transcended.
But are we not also the totality of our forebears and descendants, or, in a spatial but non-temporal image, one element of that - to us - vast total body? We must all be one 'body' - from the 'beginning' to the 'end' as perceived in the time concept, one vast body of which each (to us) individual may be likened to a cell.
However, to transcend the temporal concept while retaining the spatial seems to have little sense, save that it is easier to conceive. Our notion of timelessness is just immobility, what we describe as 'time standing still'. But spacelessness is harder on the mind. To deprive the vast body, which the removal of time has left on our hands, of its spatial character, is to reduce it to nullity or void, for even the tiniest point we can imagine occupies space.
'Body' implies 'matter', and matter implies extension in space. To follow this concept leads us beyond the boundaries of our mind and into the region of unicity in which we really are.
