text: Hindu tradition The appearance or birth of Airavata varies according to different Hindu texts. In the Ramayana, Airavata was born to Iravati (descendant of the sage, Kashyapa) whereas, the Vishnu Puran notes that Airavata was born from the churning of the ocean of milk.   According to the Matangalila, Airavata was born when Brahma sang sacred hymns over the halves of the egg shell from which Garuda hatched, followed by seven more male and eight female elephants. Prithu made Airavata king of all elephants. One of his names means "the one who knits or binds the clouds" since myth has it that these elephants are capable of producing clouds. The connection of elephants with water and rain is emphasized in the mythology of Indra, who rides the elephant Airavata when he defeats Vritra.
  It is believed that the elephant guards one of the points of compass. Airavata also stands at the entrance to Svarga, Indra's palace. In addition, the eight guardian deities who preside over the points of the compass each sit on an elephant (world elephant). Each of these deities has an elephant that takes part in the defense and protection of its respective quarter. Chief among them is Airavata of Indra. There is a reference to Airavata in the Bhagavad Gita:
  Airavata is also known for being the cause of the churning of the ocean of milk. Once sage Durvasa presented a garland to Indra, who passed it on to Airavata. The elephant then threw the garland on to the ground, which angered Durvasa and resulted in the demigods to be "subject to old age and death." Reversing the curse required the devas to retrieve the nectar of immortality by churning the ocean of milk.
