The syllable gu means darkness, ru light. Guru disperses the darkness and brings enlightenment. The notion of guru is full of deep sense. He is not a usual guide. He is a spiritual teacher that teaches the way of life and not only how to earn for this life. He passes the knowledge about the spirit, and the one who gets this knowledge is shishya (pupil). The relationship between guru and shishya is special; it is something more than a relationship between the child and the parents, husband and wife, or among friends. Guru is free from egotism. With devotion, without looking for fame or benefits, he guides the pupil towards the ultimate goal. He shows the paths of God and watches the improvements in learning and in the discipline leading him through this path. With love, he awakens trust in him, devotion, discipline, deep understanding, and enlightenment. Believing in his student, the guru does his best for the knowledge to be absorbed. He encourages him to ask questions, learning the truth by analyzing and questioning. The student should have needed qualifications such as high type of awareness and advanced spiritual development; he has to have trust, love, and devotion for his “guru” (Iyengar 2005a: 9–11).
