Om Namah Shivaya (Devanagari: ; IAST: Om Namaḥ Śivāya) is one of the most popular Hindu mantras and the most important mantra in Shaivism. Namah Shivaya means "O salutations to the auspicious one!", or “adoration to Lord Shiva". It is called Siva Panchakshara, or Shiva Panchakshara or simply Panchakshara meaning the "five-syllable" mantra (viz., excluding the Om) and is dedicated to Shiva. This Mantra appears as 'Na' 'Ma' 'Śi' 'Vā' and 'Ya' in the Shri Rudram Chamakam which is a part of the Krishna Yajurveda and also in the Rudrashtadhyayi which is a part of the Shukla Yajurveda. Origin of the mantra This mantra is present in the Shri Rudram Chamakam, which is part of the Krishna Yajurveda. Shri Rudram Chamakam is taken from two chapters in fourth book of Taittiriya Samhita (TS 4.5, 4.7) of Krishna Yajurveda. Each chapter consist of eleven anuvaka or hymns. Name of both chapters are Namakam (chapter five) and Chamakam (chapter seven) respectively. The mantra appears without the initial Om in the eighth hymn of Namakam(TS 4.5.8.1) as Namaḥ śivāya ca śivatarāya ca (Sanskrit: ). This means "Salutations unto Śiva the auspicious one, unto Śivatara the one than whom none more auspicious can exist". This mantra also appears in the Rudrashtadhyayi, a part of the Shukla Yajurveda. In the Rudrashtadhyayi, the mantra appears in the 5th chapter (also known as Namakam) verse 41. Translations among different traditions Namah Shivaya means "Adoration to Lord Shiva"; this is preceded by the devotional syllable "Om". In Siddha Shaivism and Shaiva Siddhanta Shaivism traditions, Namah Shivaya is considered as Pancha Bodha Tatva of Lord Shiva and his universal oneness of five elements: Na sound represents earth Ma sound represents water Śi sound represents fire Vā sound represents Pranic air Ya sound represents sky or ether Its total meaning is that "universal consciousness is one". In Shaiva Siddhanta, the five letters also represent: Na is the Lord's concealing grace Ma is the world Śi stands for Shiva Vā is His revealing grace Ya is the Ātman or soul The Tirumantiram (a scripture in Shaiva Siddhanta) announces that "His feet are the letter Na. His navel is the letter Ma. His shoulders are the letter Śi. His mouth, the letter Vā. His radiant cranial center aloft is Ya. Thus is the five-lettered form of Shiva.": Tirumantiram 941.
