Just like the existence of balloon depends upon the “pneuma” within it, a human being exists with the incorporeal substance ” ether ” the soul in it.The balloon can  feel its soul  vividly when it is in hot  climate /environment  because the pneuma exerts a pressure from within and a human being can feel their soul when they are in prayer or in deep meditation.Even when the balloon rupture & ceases to exist,its pneuma exists, Similarly soul exists even after the death of the  the human being.The Soul is immortal.
