ब्रह्मकृत-ईशानस्तवः तथा विश्वरूपदेवी-प्रकृतिरहस्योपदेशः
प्राह देववृषं ब्रह्मा ब्रह्माणं चात्मसंभवम् रहस्यं सर्वमन्त्राणां पावनं पुष्टिवर्धनम्
prāha devavṛṣaṃ brahmā brahmāṇaṃ cātmasaṃbhavam rahasyaṃ sarvamantrāṇāṃ pāvanaṃ puṣṭivardhanam
ബ്രഹ്മാവ് ദേവവൃഷനോടും ആത്മസംഭവനായ ബ്രഹ്മനോടും പറഞ്ഞു—ഇത് സർവമന്ത്രങ്ങളുടെ രഹസ്യസാരം; ഇത് പാവനവും പുഷ്ടിവർധകവുമാണ്.
Suta (narrating the internal account of Brahmā’s transmission)
It frames the Shiva-oriented mantra-teaching as a guarded “rahasya” whose japa and remembrance purify the worshipper and generate puṣṭi—supporting both inner sādhana and the stability needed for Linga-pūjā.
By calling the teaching the essence of all mantras and inherently purifying, it implies Shiva-tattva as Pati—the supreme sanctifier whose mantra is not merely sound but a liberating principle that loosens pāśa (bondage) from the paśu (soul).
Mantra-rahasya practice—especially japa and disciplined recitation within a Shaiva (Pāśupata-aligned) framework—emphasizing purification (pāvana) and the cultivation of steadiness and vitality (puṣṭi).
