Devi

Devi (full name: Vedisa-Mahadevi Sakyakumari) was, according to the Ceylonese chronicles, the first wife of the third Mauryan emperor Ashoka. She was also the mother of Ashoka's first two children - his son, Mahendra, and daughter, Sanghamitra, both of whom played important roles in the spread of Buddhism to other countries. She is also remembered for the Sanchi Stupa.

Origin

According to the Ceylonese chronicles, Ashoka's first wife was the daughter of a merchant of Vedisagiri, Devi by name, whom Ashoka had married while he was Viceroy at Ujjain. The Mahabodhivamsa (a Ceylonese source) calls her Vedisa-Mahadevi and a Sakyani or a Sakyakumari as being the daughter of a clan of the Sakyas who had immigrated to Vedisa nagaram out of fear of Vidudabha menacing their mother country.

This would make her a relative of the Buddha's family or clan, as he also belonged to a clan of the Sakyas. However, this connection between Devi and the Sakyas was probably a fabrication on the part of the Ceylonese chroniclers, who naturally attempted to find some relationship between her son, Mahendra, the first historically known missionary of Buddhism to Ceylon and the family of the Buddha. It seems much more feasible that Devi was merely the daughter of a local merchant of Vedisa.

Marriage

Devi and Ashoka shared a close and loving relationship unlike the usual dynastic arrangements. She gave Ashoka his first two children - the boy Mahendra, born in about the year 285 BCE, and the girl Sanghamitra, born about three years later. Yet, Devi failed to convert Ashoka to Buddhism and he left her and their children in Vedisa when he was finally recalled to Pataliputra. Thus, Devi did not follow Ashoka as sovereign to Pataliputra, for there his Chief Queen (agramahisi) was his wife, Asandhimitra. It would have been unfitting for a prince of the House of Maurya to have a merchant's daughter for a spouse, and a more suitable wife was found for Ashoka in Princess Asandhimitra, who became his chief queen and held that position for the majority of his reign.

Devi is described as having caused the construction of the Great Vihara of Vedisagiri, probably the first of the monuments of Sanchi and Bhilsa. This explains why Ashoka selected Sanchi and it's beautiful neighbourhood for his architectural activities. Vedisa also figures as an important Buddhist place in earlier literature.
