Below are the Pancha-Brahma mantras that come to us from the Taittiriya Aranyaka (X.17-21) of the Krsna Yajurveda. The tenth chapter of the Taittiriya Aranyaka is also called the Mahanarayan Upanishad. Therefore, these mantras can also be said to belong to the Mahanarayana Upanishad (17-21). These mantras are used frequently in Shiva Pujas, and alluded to often in Shiva worship protocols and manuals. The Pancha-Brahma mantras exalt Shiva through His five forms (faces) – Sadyojata, Vamadeva, Aghora, Tatpurusa and Isana. The five faces or forms of Shiva represent the five functions or acts (panchakrityas) – creation, sustenance, dissolution, concealing grace and revealing grace, respectively. The five forms or faces of Shiva also correspond to the five syllables in the holy pentasyllabic mantra – na-mah-shi-vā-ya. Note that the Tatpurusa mantra is but the Rudra Gayatri.

sadyojātaṁ prapadyāmi sadyojātāya vai namo namaḥ
bhave bhave nāti bhave bhavasva māṁ bhavodbhavāya namaḥ

Do not consign me to birth after birth;
Guide me beyond birth, I bow to the Causer of birth.
