The word necromancy is adapted from Greek nekromanteía, a compound of Ancient Greek (nekrós), "dead body", and manteía, meaning 'divination by means of'. This compound form was first used by Origen of Alexandria in the 3rd century AD. The Classical Greek term was nekyia, from the episode of the Odyssey in which Odysseus visits the realm of the dead. Nekyia, however, is not a Greek word, but Sanskrit and it means a cluster, collection, multitude, referring to Nirukta, which provides insight into the hidden content of the Veda, called Vendanga, which is referring to the number 6, the number of the man. Just like the limb of the body, they perform various supportive functions in the study of Veda.
There are six Vedas, called Vedangas, comprising of Siksha, Chhanda, Vyakarana, Nirukta, Jyotisha and Kalpa. The Veda contains mysterious symbolism, not understood at all, which is obvious from Greek mythology, the interpretation of the Sanskrit words becoming spells, witchcraft and mythology turned science upside down.
