This God of knowledge and the remover of obstacles is also the older son of Lord Shiva. Lord Ganesha is also called Vinayak ( knowledgeable ) or Vighneshwer (god to remove obstacles). He is worshipped, or at least remembered, in the beginning of any auspicious performance for blessings and auspiciousness.
Today, Ganesha is the most-worshipped divinity in India. Worship of Ganesha is considered complementary with the worship of other forms of the divine, and various Hindu sects worship him regardless of other affiliations.
