प्रणवमहिमा — The Greatness of the Praṇava (Om) as Śiva
अकारश्चाप्युकारोयं मकाराश्च त्रयं क्रमात् । तिस्रो मात्रास्समाख्याता अर्द्धमात्रा ततः परम्
akāraścāpyukāroyaṃ makārāśca trayaṃ kramāt | tisro mātrāssamākhyātā arddhamātrā tataḥ param
依次为‘a’、‘u’、‘m’——此三者被宣说为“唵”(Oṃ)的三种音量(mātrā);其后更有半音量(ardhamātrā),乃微妙超越之境。
Lord Shiva (teaching in the Kailāsa Saṃhitā, a philosophical discourse context)
Tattva Level: pati
Shiva Form: Sadāśiva
Mantra: oṃ = a + u + m (+ arddhamātrā)
Type: gayatri
Role: teaching
It defines Oṃ as three articulated mātrās—A, U, M—culminating in the arddha-mātrā, indicating the move from expressed sound to the silent, subtle awareness where Pati (Śiva) is realized beyond pasha and pashu.
In Śaiva practice, Oṃ supports saguna upāsanā (worship with form) by steadying mind and breath; the half-mātrā points to the linga’s deeper import—Śiva as the formless ground (nirguṇa) transcending the manifested syllables while still being approached through them.
Japa and dhyāna on Oṃ: contemplate A–U–M in sequence, then rest attention in the arddha-mātrā (the quiet after sound), aligning breath and mind before or alongside Panchākṣarī (Oṃ Namaḥ Śivāya) recitation.
