Namaste, if i die someday what will happen to my body ? will i be born again ? what if i don't want to be born again ?
The body gets cremated. it is the soul that reincarnates. You, as an individual, personality, are gone forever. That is all temporary. But within time, the soul reincarnates, only to develop a new physical body, ego, intelligence, personality around it. That pattern just keeps repeating itself until our (by this I mean soul) lessons are learned, karms are fulfilled, and we no longer need to reincarnate.
Death, according to Hinduism, is a series of changes through which an individual passes. Hinduism believes in the rebirth and reincarnation of souls. The souls are immortal and imperishable. Each Life experience on earth and each incarnation of soul offers the jiva an opportunity to learn and overcome its inconsistencies. The soul therefore needs to be born again and again till it overcomes its state of dillusion and realizes its completeness. According to Hinduism, dying may be compared to falling asleep and after-death experiences to dreams. The thoughts and actions of the waking state determine the nature of our dreams. Similarly, after death the soul experiences the results of the thoughts it entertained and the actions it performed during its life on earth.
