The term "guru" can refer to a teacher or guide in Hinduism, Buddhism, and other Indian religions. In these traditions, a guru is seen as someone who has attained spiritual knowledge and wisdom, and who can help others achieve the same. The relationship between a guru and disciple is considered very important in these traditions, as it is believed to be a key factor in spiritual growth and enlightenment. Outside of religious contexts, the term "guru" may be used more broadly to refer to an expert or authority in a particular field.
