Kashyapa

1. Another tale of Ganesha's birth relates to an incident in which Shiva slew Aditya, the son of a sage. Shiva restored life to the dead boy, but this could not pacify the outraged sage Kashyapa, who was one of the seven great Rishis. Kashyap cursed Shiva and declared that Shiva's son would lose his head. When this happened, the head of Indra's elephant was used to replace it. Still another tale states that on one occasion, Parvati's used bath-water was thrown into the Ganges, and this water was drunk by the elephant-headed Goddess Malini, who gave birth to a baby with four arms and five elephant heads. The river goddess Ganga claimed him as her son, but Shiva declared him to be Parvati's son, reduced his five heads to one and enthroned him as the controller of obstacles (Vignesha).
2. Mahotkata Vinayaka (Mahotkaţa Vināyaka), who has ten arms and a red complexion. Different sources list his mount (vāhana) as either an elephant or lion. He was born to Kashyapa (Kaśyapa) and Aditi in the Krita yuga. The name Kāśyapaḥ (descendant of Kaśyapa) for Ganesha refers to this incarnation. This incarnation killed the demon brothers Narantaka (Narāntaka) and Devantaka (Devāntaka), as well as the demon Dhumraksha (Dhūṃrākşa).
