Here is an excerpt from the writing of the 15th Gyalwa Karmapa Khakyab Dorje (1871–1922), the Head Lama of the Karma Kagyu tradition, on the meaning and benefits of Chenrezig’s mantra OM MANI PEME HUNG. Karmapa has given this commentary on a Four-Armed Chenrezig practice. The first syllable, OM, is white; it is the manifestation of Lord Chenrezig’s 5 wisdoms and perfect meditation.
