Vighneshvara-Prashna and Deva-Krita Shiva-Stava
Adhyaya 104
ओङ्कारे त्रिविधं रूपम् आस्थायोपरिवासिने पीताय कृष्णवर्णाय रक्तायात्यन्ततेजसे
oṅkāre trividhaṃ rūpam āsthāyoparivāsine pītāya kṛṣṇavarṇāya raktāyātyantatejase
Habitando na sílaba Oṃ, Ele assume uma forma tríplice—morando acima como o Senhor transcendente; manifestando-se como amarelo, como de tonalidade escura e como vermelho—Ele, de fulgor incomensurável.
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.
