A true guru is a enlighened master who guides his or her disciple on the spiritual path. The function of a true guru is two-fold: first, he or she explains the scriptures and guides the disciple on the spiritual path; second, the guru teaches by setting an example with the daily acts of his or her own life. Sometimes by words and sometimes in silence, a true guru purifies the spirit of the disciple. According to Hindu view, a disciple who obeys his or her guru in humility and in reverence attains the highest knowledge by the grace of God. In Hinduism a guru-disciple relationship is the most sacred relationship in life. The Katha Upanishad thus declares: “To many it is not given to hear of the Self [God within]. Many, though they hear of it, do not understand it. Wonderful is he who speaks of it. Intelligent is he who learns of it. Blessed is he who, taught by a good teacher (guru), is able to understand it....”
