ATMA ( आत्मा )
Atma is the source of “Life Energy”, which is present in every living organism (Plants to animals to humans). It is “Invisible & Non-physical” energy yet having infinite knowledge, infinite power, infinite bliss, peace etc. It has a permanent state, with no beginning or end & is not affected by anything such as from fire, atom bombs, weapons, chemicals etc. It “auto-provides” needed energy for existence, maintenance and functioning of the body with mind of a living being.
SOUL ( रूह / जीवात्मा )
ATMA + KARMIC BODY (KARMA with its karmic memory, mentality & intellect) : When we die, the “soul” leaves the present body & occupies another body, as per “Karma” of the living-being.
BODY ( शरीर ) / Organism ( जीव )
