What is this fictitious thing called Soul, which all religions except Buddhism believe in? Some believe equate soul with life, others think it is mind and that heart is the seat of it. Let us consider the following:
1) Soul cannot be in the heart. If so, a funny situation will of exchanging souls will arise while transplanting hearts. 2) Soul cannot be in the head as the headless body of some insects can continue to live after decaptition. 3) Soul cannot be diffused in the whole body as bodies of lower animals which can take oxygen through body can be fragmented into small pieces and each piece is capable of growing into a new organism. 4) Some times human fetus in womb may divide into two, three or four and develop into identical off-springs. In that case will be girls or boys have only part of a soul? 5) A dead body can be revived artificially even after several years as it can be done in cryogeny. Does the departed soul re-enter the resuscitated body? In that case, where was the soul in the intervening period? 6) If a person has several grafted organs and tissues in his body, will that person possessing fragments of several souls?
So, it is clear that there is nothing called soul and consequently the concept of saving of souls (riddance from the cycle of births and re-births as per Hindu mythology) is also an absurd concept.
