Ganesa is probably the most popular god in India among the Hindus and was accepted by the Buddhist and Jaina as also by the Tantrics. His very therianthropic form evokes curiosity and many attempts have been made to explain it on the basis of literary testimony which, however, is a later fabrication. Relevant archaeological testimony, however, was largely ignored. But it should be emphasized that only archaeology offers reliable data which has been employed here for the first time. It very convincingly explains the rise of the elephant-headed divinity from a sacred animal and an animal totem to the exalted position of a cult deity in Hindu pantheon. This long journey of the god from gaja to gana to Ganesa to Maha-Ganesa and a cult deity, as great as Siva and Vishnu, is truly amazing. His popularity in a large measure is due to his being a vighna-karta (obstacle-creator) changing into a vighna-harta (obstacle-remover), when properly propitiated. Wherever Indians went and settled, they took Ganesa with them for removing obstacles, and therefore Ganesa is the only divinity who can truly be called the God of Asia.
