Derived from the
Sanskrit word, gu, which means “darkness,” and ru, which
translates as “remover,” the guru is more than just a
teacher, but someone who removes spiritual darkness and paves the way
to enlightenment and unity with Brahman. Om is the sound that
represents Brahman, the universe and essence of creation. Guru om can be chanted by itself, as part of a longer mantra or hymn, or as individual components in a mantra.
