Ganesha (Sanskrit: गणेश; IAST: Gaṇeśa; listen (help·info)), also spelled Ganesa or Ganesh, also known as Ganapati (Sanskrit: गणपति, IAST: gaṇapati), Vinayaka (Sanskrit: विनायक; IAST: Vināyaka), and Pillaiyar (Tamil: பிள்ளையார்), is one of the deities best-known and most widely worshipped in the Hindu pantheon.[5] His image is found throughout India and Nepal.[6] Hindu sects worship him regardless of affiliations.[7] Devotion to Ganesha is widely diffused and extends to Jains, Buddhists, and beyond India.[8]
Although he is known by many other attributes, Ganesha’s elephant head makes him particularly easy to identify.[9] Ganesha is widely revered as the Remover of Obstacles[10] and more generally as Lord of Beginnings and Lord of Obstacles (Vighnesha (Sanskrit: विघ्नेश; IAST: Vighneśa), Vighneshvara (Sanskrit: विघ्नेश्वर; IAST: Vighneśvara)),[11] patron of arts and sciences, and the deva of intellect and wisdom.[12] He is honoured at the beginning of rituals and ceremonies and invoked as Patron of Letters during writing sessions.[13] Several texts relate mythological anecdotes associated with his birth and exploits and explain his distinct iconography.
Ganesha emerged a distinct deity in clearly recognizable form in the 4th and 5th centuries CE, during the Gupta Period, although he inherited traits from Vedic and pre-Vedic precursors.[14] His popularity rose quickly, and he was formally included among the five primary deities of Smartism (a Hindu denomination) in the 9th century. A sect of devotees called the Ganapatya (Sanskrit: गाणपत्य; IAST: gāṇapatya), who identified Ganesha as the supreme deity, arose during this period.[15] The principal scriptures dedicated to Ganesha are the Ganesha Purana, the Mudgala Purana, and the Ganapati Atharvashirsa.
