This mantra (chant) is associated with qualities of prayer, divine-love, grace, truth, and blissfulness. When done correctly, it calms the mind and brings spiritual insight and knowledge. It also keeps the devotee close to Shiva and within His protective global fellowship.
Traditionally, it is accepted to be a powerful healing mantra beneficial for all physical and mental ailments. Soulful recitation of this mantra brings peace to the heart and joy to the Ātman or soul.

The nature of the mantra is the calling upon the higher self; it is the calling upon Shiva.
