Guru Purnima (Poornima) is a spiritual tradition in Indian religions dedicated to spiritual and academic teachers, who are evolved or enlightened humans, ready to share their wisdom, with very little or no monetary expectation, based on Karma Yoga. It is celebrated as a festival in Nepal by the Nepalese Hindus and Buddhists. This festival is traditionally observed by Hindus, Buddhists and Jains to revere their chosen spiritual teachers / leaders and express their gratitude. The festival is celebrated on the full moon day (Purnima) in the Hindu month of Ashadha (June–July) as it is known in the Hindu calendar of India and Nepal.
The celebration is marked by spiritual activities and may include a ritualistic event in honor of the Guru, Guru Pooja. The Guru Principle is said to be a thousand times more active on the day of Guru Purnima than on any other day. The word Guru is derived from two words, gu and ru. The Sanskrit root gu means darkness or ignorance, and ru denotes the remover of that darkness. Therefore, a Guru is one who removes the darkness of our ignorance. Gurus are believed by many to be the most necessary part of life. On this day, disciples offer pooja (worship) or pay respect to their Guru (spiritual guide). In addition to having religious importance, this festival has great importance for Indian academics and scholars. Indian academics celebrate this day by thanking their teachers as well as remembering past teachers and scholars.
