Vighneshvara-Prashna and Deva-Krita Shiva-Stava
Adhyaya 104
ओङ्कारे त्रिविधं रूपम् आस्थायोपरिवासिने पीताय कृष्णवर्णाय रक्तायात्यन्ततेजसे
oṅkāre trividhaṃ rūpam āsthāyoparivāsine pītāya kṛṣṇavarṇāya raktāyātyantatejase
Im Laut Oṃ verweilend, nimmt Er eine dreifache Gestalt an—oben wohnend als der transzendente Herr; erscheinend in Gelb, in dunkler Färbung und in Rot—Er, von unermesslichem Glanz.
Suta Goswami (narrating Linga Purana teachings to the sages of Naimisharanya)
It identifies Oṃ (Pranava) as the subtle seat of the Linga-principle: the worshipper contemplates Shiva as the transcendent Pati who manifests in a threefold way, making Omkara-dhyana a direct support for Linga-upasana.
Shiva is portrayed as atyanta-tejas (limitless consciousness-radiance) who remains ‘above’ as transcendent, yet expresses Himself through differentiated appearances (the three colors/forms), indicating both nirguna transcendence and saguna manifestation.
Pranava-upasana: meditative absorption on Oṃ as Shiva’s sonic body, used in Pashupata-oriented contemplation to loosen pasha (bondage) and steady the pashu (soul) in awareness of the Pati.
