Guru

Guru ( ; IAST: ''guru;'' Pali'': garu;'' Punjabi: ਗੁਰੂ (Gou-roo)) is a Sanskrit term for a "mentor, guide, expert, or master" of certain knowledge or field. In pan-Indian traditions, a guru is more than a teacher: traditionally, the guru is a reverential figure to the disciple (or ''shisya'' in Sanskrit, literally ''seeker [of knowledge or truth'']) or student, with the guru serving as a "counselor, who helps mold values, shares experiential knowledge as much as literal knowledge, an exemplar in life, an inspirational source and who helps in the spiritual evolution of a student". Whatever language it is written in, Judith Simmer-Brown says that a tantric spiritual text is often codified in an obscure twilight language so that it cannot be understood by anyone without the verbal explanation of a qualified teacher, the guru. A guru is also one's spiritual guide, who helps one to discover the same potentialities that the ''guru'' has already realized.

The oldest references to the concept of ''guru'' are found in the earliest Vedic texts of Hinduism. The ''guru'', and ''gurukula'' – a school run by ''guru'', were an established tradition in India by the 1st millennium BCE, and these helped compose and transmit the various Vedas, the Upanishads, texts of various schools of Hindu philosophy, and post-Vedic Shastras ranging from spiritual knowledge to various arts. By about mid 1st millennium CE, archaeological and epigraphical evidence suggest numerous larger institutions of ''gurus'' existed in India, some near Hindu temples, where guru-shishya tradition helped preserve, create and transmit various fields of knowledge. These gurus led broad ranges of studies including Hindu scriptures, Buddhist texts, grammar, philosophy, martial arts, music and painting.

The tradition of the guru is also found in Jainism, referring to a spiritual preceptor, a role typically served by a Jain ascetic. In Sikhism, the ''guru'' tradition has played a key role since its founding in the 15th century, its founder is referred to as Guru Nanak, and its scripture as Guru Granth Sahib. The guru concept has thrived in Vajrayāna Buddhism, where the tantric guru is considered a figure to worship and whose instructions should never be violated. Provided by Wikipedia
