Ganesha or Ganesh, also known as Ganapati and Vinayaka, is one of the best-known and most worshipped deities in the Hindu pantheon. His image is found throughout India, Nepal, Sri Lanka, Thailand, Bali (Indonesia) and Bangladesh, and in countries with large ethnic Indian populations including Fiji, Mauritius and Trinidad & Tobago. Devotion to Ganesha is widely diffused and extends to even Jains & Buddhists. Ganesha is also popular in Japan.
Although Ganesha has many attributes, he is readily identified by his elephant head. He is widely revered, more specifically, as the remover of obstacles, and also as the patron of arts and sciences, and the god of intellect and wisdom.
As the god of beginnings, he is honoured at the start of all rites and ceremonies.
In Indian Iconography Ganesha is a popular figure in Indian art.
Ganesha is Vighneshvara the Lord who is remover of Obstacles, both in our material and spiritual pursuits. He is popularly worshipped as a remover of obstacles, though traditionally he also places obstacles in the path of those who need to be tested for their faith in Him. Hence, the Hindus worship Him before they begin anything new.
Ganesha as already mentioned is also considered to be the Lord of letters and learning. The concept of Buddhi (Intelligence ) is closely associated with the personality of Ganesha, especially in the Puranic period, when many stories stress his cleverness and love of intelligence.
