Hinduism
The white elephant is considered to belong to the god Indra. The name of the elephant is Airavata and it is a flying elephant. Airavata is made the King of all elephants by Lord Indra.
King Bimbisara had one such white elephant, which was conquered by him from the forest when the elephant was in his Musth period, and named him Sechanaka which means "watering" as the elephant used to water the plants by himself without any prior training. It is said that the cost of this elephant was more the half of Magadha. Later he gifted it to his son Vihallakumara, this envied his other son Ajatasatru who tried to snatch it many times, which later resulted in two of the most terrible wars in history called Mahasilakantaka & Ratha-musala. (see Ajatasatru).
