Ṣaḍvidhārtha-Parijñāna: Praṇavārtha and the Sixfold Unity of Meaning (षड्विधार्थपरिज्ञानम् / प्रणवार्थपरिज्ञानम्)
यंत्ररूपेणोपदिष्टः प्रणवश्शिववाचकः । समष्टिः पंचवर्णानां बिंद्वाद्यं यच्चतुष्टयम्
yaṃtrarūpeṇopadiṣṭaḥ praṇavaśśivavācakaḥ | samaṣṭiḥ paṃcavarṇānāṃ biṃdvādyaṃ yaccatuṣṭayam
The Praṇava (Oṁ), which signifies Śiva, is taught in the form of a yantra. It is the unified totality of the five sacred syllables, together with the fourfold set beginning with the bindu, the point of origin.
Lord Shiva (as teacher of mantra and yoga in Kailāsasaṃhitā)
Tattva Level: pati
Shiva Form: Sadāśiva
Mantra: ॐ (प्रणवः) — शिववाचकः; (पञ्चवर्णसमष्टिः)
Type: panchakshara
It identifies Oṁ (Pranava) as directly expressive of Shiva and presents it as a complete mantric reality—uniting the pañcākṣara with subtle inner principles like bindu—supporting Shaiva Siddhanta’s path of mantra leading the bound soul (paśu) toward Shiva (Pati).
By describing Pranava as ‘yantra-formed,’ the verse links sound (mantra) with form (yantra/linga as a support). Saguna worship uses such supports to steady the mind, through which devotion and awareness mature toward Shiva’s transcendent reality.
Japa of Oṁ and/or the pañcākṣara (Oṁ Namaḥ Śivāya), done with yantra-dhyāna—contemplating bindu and the mantric structure—especially as a steady daily sādhanā (and traditionally intensified on Mahāśivarātri).
