उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
ब्रह्माधिदैवतं छन्दो बृहती चाङ्गिरा ऋषिः यकारो रक्तवर्णश् च स्थानम् ऊर्ध्वं मुखं विराट्
brahmādhidaivataṃ chando bṛhatī cāṅgirā ṛṣiḥ yakāro raktavarṇaś ca sthānam ūrdhvaṃ mukhaṃ virāṭ
Para sa sangkap na mantriko na ito, si Brahmā ang ipinahahayag na namumunong diyos; ang sukat ay Bṛhatī; at ang ṛṣi ay si Aṅgiras. Ang bīja ay “ya”, kulay-pula; ang pook nito ay sa itaas, at ang mukha nito ay ang kosmikong Virāṭ.
Suta Goswami (narrating a mantra-anga specification within the Linga Purana’s Shaiva ritual framework)
It gives the viniyoga-style identifiers—deity, metre, seer, bija, color, and locus—used to correctly apply mantra-nyāsa in Linga-pūjā, aligning the sādhaka’s body and awareness to the rite.
By assigning the ‘face’ as Virāṭ and the locus as ‘above’, it frames worship as moving from the embodied cosmos (Virāṭ) upward toward the transcendent Pati (Śiva), who liberates the paśu from pāśa through right mantra and discipline.
Mantra-viniyoga and nyāsa: the practitioner contemplates the seer (Aṅgiras), metre (Bṛhatī), presiding principle (Brahmā), and the red “ya” bija placed in an upward locus—supporting Pāśupata-oriented purification and concentration.
