The sacred syllable OM. Four sounds that blend together: 'Aaah' in the pelvic floor for the physical body / 'Ohhh' in the back of the heart for the emotional center / 'Mmmmm' in the head for the intellect –followed by the sound of silence for the Spirit. This short, guided session has us chanting the sound 27 times, which is 1/4 of 108. 108 is a sacred number in yogic philosophy, so you can repeat the class 4 times and have a full OM KAUR practice (chanting the sound 108 times).
