उमामहेश्वरव्रतं—पञ्चाक्षरमन्त्रस्य माहात्म्यं, न्यासः, जपविधिः, सदाचारः, विनियोगः
त्वदीयं प्रणवं विद्धि त्रिमात्रं प्लुतमुत्तमम् ओङ्कारस्य स्वरोदात्त ऋषिर्ब्रह्म सितं वपुः
tvadīyaṃ praṇavaṃ viddhi trimātraṃ plutamuttamam oṅkārasya svarodātta ṛṣirbrahma sitaṃ vapuḥ
このプラナヴァは汝に属するものと知れ。三マートラーより成り、長く引き伸ばして唱える最上のオームである。そのオーンカーラの声調はウダーッタ、聖見者(ṛṣi)はブラフマー、形相は白く輝く—それはパティ(シヴァ)の清浄光が、パシュをパーシャの縛りから解き放つことを示す。
Suta Goswami (narrating an internal Shaiva teaching on Pranava)
It links Linga-upāsanā to the Pranava (Oṁ) as Śiva’s own sonic form—recited as a three-mātrā, prolonged mantra—making Omkara the seed (bīja) contemplation behind Linga-pūjā.
Śiva is implied as Pati whose pure, luminous (white) form is expressed as Oṅkāra; meditating on this purity is a means for the paśu (soul) to loosen pāśa (bondage) through mantra-jñāna.
Vedic-correct japa/uccāraṇa of Oṁ with three mātrās and a prolonged (pluta) recitation, maintaining the proper udātta intonation—used as a Pāśupata-oriented mantra practice supporting inner absorption (dhyāna).
