It is said in our Hinduism that the soul never dies, it are immortal. Only our outer body dies and this thing has been proved scientifically that when a scientist had kept the dying person in a glass cage.

Just at the moment he died, the glass cracked. This showed that the soul is immortal and it came out of the body and went away. And, the weight of the soul in our body is exactly 21 grams, so there is a difference of 21 grams before and after death. This weight loss is due to the weight of the soul. I feel that when the soul is immortal, then the reincarnation may be possible somewhere.
