In Siddha Yoga, SGNMKJ is used as an opening and/or closing ritual group utterance, signifying the enclosed period of time as a special or sacred event. The careful opening of hands, then bringing them together before the heart in the 'namaste' pose, as prelude to SGNMKJ, makes participation much more visible, since a mouth need not move much to speak, while hands before the heart are much more prominently visible to all as a symbol of group participation.
Potential negative implications of such group behavior should be understood and carefully avoided.
