Here a Buddhist form of the popular Hindu god Ganesha has been depicted. In Brahmanism Ganesha clears away obstacles both spiritual and physical and bestows wealth, prosperity and knowledge. In Hindu rituals and worships, his puja precedes the pujas of all other gods and goddesses, for which he is given the epithet - Agrapujya. Nearly in all Hindu practices his worship occurred at the beginning of any religious ceremony and on special occasions. Ganesha is worships by Buddhists in different forms. However in Tantric Buddhism there is a school that sees Ganesha as a hindrance or vighna. This led to the creation of the Tantric Buddhist divinity Vighnantaka, the "Subduer of Vighna," whereby we see this divinity trample Ganesha underfoot, standing or dancing on him. But on other hand Ganesha is popularly worships as remover of obstacles, and as a protector deity. His cult is very popular in Nepal, Japan, and Tibet and in many countries including India. Thus Ganesha is very popular in Asia. His birthday, 4th day of the month of Bhadrapada of the Hindu Lunar calendar (August-September), is a cause for great celebrations and pujas. His name, Ganesha, "Supreme Master-Lord of the Ganas," or Ganapati, "Lord of the Ganas", describes his overlordships of the ganas. A gana is a spiritual beings, translated here as "Categories" but which also carries the notion of a vast "multitude" or "host" of beings. They are the characteristics, categories, and conditions that create everything in the mundane, material world. And, since there is at least one gana for every such category, they are virtually infinite in number. As master of the ganas, Ganesha controls the characteristics, categories, and conditions of everything. On one hand, he overcome any obstacle, hindrance, or diversion, while on the other hand; he can provide all necessary health, security, and well being to liberate one from mundane cares of the day-to-day existence. In Nepalese Buddhism, Ganesha is always the benefactor and protector. However in Tibetan Buddhism he can be the obstacle as well as the one who overcomes obstacles.
