Skanda Purana — Mahesvara Khanda, Shloka 69
अर्धमात्रा च या मूर्ध्नि परमः स सदाशिवः । एवमोंकारमाहात्म्यं श्रुतिरेषा सनातनी
ardhamātrā ca yā mūrdhni paramaḥ sa sadāśivaḥ | evamoṃkāramāhātmyaṃ śrutireṣā sanātanī
Und die halbe Silbe (ardhamātrā), die am Scheitel ruht, ist das Höchste—Sadāśiva. So ist die Größe des Oṃkāra: dies ist die ewige Lehre der Śruti.
Lomaharṣaṇa (Sūta) to the sages (deduced from Māheśvara-khaṇḍa narrative convention)
Scene: A yogin or teacher intones Oṃ; A-U-M appear as three luminous bands, while a subtle crescent-dot (ardhamātrā/bindu) rises to the crown, revealing Sadāśiva as a serene, five-faced or effulgent form dissolving into pure light.
FAQs

No location is specified; the focus is mantra-metaphysics and Śaiva theology of Oṃ.
No explicit prescription; it supports contemplative Oṃ-upāsanā (meditation on Oṃ and its subtle culmination).
