A guru is a spiritual teacher, someone who leads a disciple to wisdom and self-realization, imparts knowledge on the disciple, or guides the disciple to divinity. The word guru is commonly used in the Hindu, Buddhist, and Sikh traditions to indicate a religious teacher. The word originates in Sanskrit, and is formed by the syllables gu and ru. Gu indicates darkness, and ru indicates destruction. Thus, when translated directly, guru means ‘dispeller of darkness.’ This simple etymological explanation is supplemented by the postulation of numerous texts discussing the nature and role of a guru. A popular example of such a discussion would be that of the etymology of the syllables gu and ru to indicate the juxtaposition of light and dark, where ignorance is dark and knowledge, particularly spiritual knowledge, is light.
The notion of the guru dates back to a collection of ancient Indian texts known as the Upanishads. Other ancient Indian texts that discuss the concept of guru include the Bhagavad Gita, a section of the Indian epic, the Mahabharata. The Guru Gita and, less directly, the Ramayana are other ancient Indian texts addressing the role of the guru, and the disciple known as the shishya. In these texts, the ideal guru-shishya relationship is exemplified in the characters. In the Bhagavad Gita, Krishna plays the role of guru to the warrior prince Arjuna, guiding him through his uncertainty regarding morality and duty. In the Ramayana, the guru-shishya relationship is demonstrated through the hero Rama and the monkey deity Hanuman. In the Guru Gita, Lord Shiva is the guru, while his female consort Parvati is the shishya.
