Paraloka-Vidya or the science about the departed souls and their planes of living is a subject of absorbing interest. It is a Mysterious Science which contains many secrets or hidden wonders. It has intimate connection with Panchagni-Vidya or the science of transmigration propounded in the Chhandogya Upanishad. The doctrine of reincarnation or metempsychosis, transmigration of the soul and spiritualism come under the Paraloka-Vidya. Everybody is curious and anxious to know this science.
