The afterlife (also referred to as life after death) is the belief that the essential part of an individual's identity or the stream of consciousness continues after the death of the physical body. According to various ideas about the afterlife, the essential aspect of the individual that lives on after death may be some partial element, or the entire soul or spirit, of an individual, which carries with it and may confer personal identity or, on the contrary nirvana. Belief in an afterlife is in contrast to the belief in oblivion after death.
In some views, this continued existence often takes place in a spiritual realm, and in other popular views, the individual may be reborn into this world and begin the life cycle over again, likely with no memory of what they have done in the past. In this latter view, such rebirths and deaths may take place over and over again continuously until the individual gains entry to a spiritual realm or otherworld. Major views on the afterlife derive from religion, esotericism and metaphysics.
