What do major world religions teach about life after death?

Most major world religions affirm some form of existence after physical death. Christianity teaches resurrection of the body and eternal life in heaven or hell, with some traditions including purgatory. Islam similarly teaches resurrection and judgment leading to paradise or hell. Judaism has varied beliefs, generally less defined, ranging from resurrection to the soul returning to God. Hinduism and Buddhism teach reincarnation or rebirth, where the soul or consciousness cycles through multiple lives based on karma, with the ultimate goal being liberation from this cycle, called moksha in Hinduism and nirvana in Buddhism. Sikhism also teaches reincarnation with the goal of merging with God. While details differ significantly, the common thread is that death is not the absolute end.
