'Om Namah Shivaya' is the 5-syllabled Panchakshara Mantra of Shiva, while 'Hreem' is the Beej Mantra, the powerful seed sound of Mother Goddess Shakti. 'Om Hreem Namah Shivaya' thus reveres the universal parents, Shiva and Shakti, together as the Guru Tattva, the principle of wisdom present in the universe. Chanting this potent Mantra that prays to Shiva, the Divine consciousness, and Shakti, the Divine energy, regularly with devotion and faith, can even help miracles happen in devotees' lives.
