Death and After Death States
Theosophy teaches that after a person dies, the Ego and its non-physical bodies undergo a process consisting of multiple stages before reincarnating. The process may be very brief (as in young children or cases of premature death) or it can be as long as 3,000 years. Theosophical literature, particularly the Mahatma Letters, has extensive teachings about the after-death states, some of which have received validation in parapsychological studies in the past century or so.
Life Span. Each person is born with a certain quantity of life-energy like the oil in a lamp. When the oil is exhausted the person dies even if apparently healthy. When however, the life-energy is not exhausted and the person meets a violent death, then the Ego continues to be conscious and alive, minus the physical body.
