Guru
Also known as: Spiritual Teacher, Acharya
Sanskrit: guru, from gu (darkness) and ru (light), traditionally interpreted as one who dispels darkness.
A guru is a teacher in Indian spiritual tradition who has direct, lived realization of the teaching they transmit and who guides a student's spiritual development through instruction, example, and relationship over time. The term is traditionally reserved for a teacher of significant depth, used more carefully than its casual modern use.
Classical guru-disciple relationships, described as the guru-shishya tradition, typically involve sustained, personal instruction over years, distinguishing them from a workshop instructor or the more casual modern use of guru for any expert. Traditions also generally teach discernment in choosing a teacher, since the historical record includes both genuinely realized teachers and figures who exploited the position, making a student's own grounded judgment an important part of the relationship.
The word is often explained through a folk etymology, gu (darkness) and ru (one who dispels it), though scholars debate how literal this derivation is; regardless, the function described in the tradition is removing ignorance, not simply transmitting information. Contemporary usage has diluted the word to mean any expert, as in 'marketing guru,' which differs sharply from its traditional meaning: someone who has walked the path being taught and can recognize a specific student's stage and obstacles.
