The Panchakshari mantra, 'Om Namah Shivaya', is one of the most revered and powerful mantras in Hinduism, dedicated to Lord Shiva. Its textual origin is found in the Krishna Yajurveda, specifically in the Rudra Upanishad (verses 1-2), where it is revealed as the essence of all mantras. The mantra consists of five syllables: 'Na', 'Ma', 'Shi', 'Va', 'Ya', preceded by the Pranava 'Om'.
According to the Shiva Purana (Vidyeshvara Samhita, Chapter 13), each syllable corresponds to one of the five elements (earth, water, fire, air, and ether) and to the five faces of Shiva (Sadyojata, Vamadeva, Aghora, Tatpurusha, and Ishana). The beej-akshara analysis reveals that 'Na' represents the earth element and the Muladhara chakra, 'Ma' represents water and Svadhisthana, 'Shi' represents fire and Manipura, 'Va' represents air and Anahata, and 'Ya' represents ether and Vishuddha. The mantra is chanted for liberation (moksha), protection from negative forces, and the grace of Shiva.
The Shiva Purana (Rudra Samhita, Chapter 6) states that regular chanting of this mantra removes sins and grants all desires. The Mantra Mahodadhi (Chapter 2) prescribes chanting 108 times daily, preferably during Brahma Muhurta (early morning) or at dusk, facing north or east. It is also recommended to chant on Maha Shivaratri and during the month of Shravana.
Cautions include maintaining purity of body and mind, and avoiding chanting in unclean places or during impure states. The mantra is considered a maha-mantra that can be chanted by all, regardless of caste or gender, as affirmed in the Rudra Upanishad.
Salutations to the auspicious one (Shiva).
The five syllables Na-Ma-Śi-Vā-Ya correspond to the five elements (earth, water, fire, air, ether) and the five faces of Shiva. 'Na' is earth (Muladhara), 'Ma' is water (Svadhisthana), 'Śi' is fire (Manipura), 'Vā' is air (Anahata), 'Ya' is ether (Vishuddha). The Pranava Oṁ precedes them as the seed of all mantras.
