Ṣaḍvidhārtha-Parijñāna: Praṇavārtha and the Sixfold Unity of Meaning (षड्विधार्थपरिज्ञानम् / प्रणवार्थपरिज्ञानम्)
पंचमादि समारभ्य सद्योजाताद्यनुक्रमात् । उर्द्ध्वांतमीशानांतं च मुखपंचकमीरितम्
paṃcamādi samārabhya sadyojātādyanukramāt | urddhvāṃtamīśānāṃtaṃ ca mukhapaṃcakamīritam
पञ्चमात् आरभ्य, सद्योजाताद्यनुक्रमेण, ऊर्ध्वान्तं ईशानान्तं च मुखपञ्चकम् इति निरूपितम्॥

Tattva Level: pati
Shiva Form: Sadāśiva
It establishes the Pañcamukha (five-faced) doctrine of Śiva—an ordered revelation of His fivefold manifestation, culminating in Īśāna as the supreme, upward-facing principle, supporting Shaiva Siddhanta contemplation of Pati (the Lord) as both immanent and transcendent.
The five faces are commonly contemplated in Śiva-liṅga worship as the Lord’s saguna revelation for meditation and mantra-japa, while pointing beyond form to Īśāna as the transcendent summit—thus uniting saguna upāsanā with the ascent toward nirguṇa realization.
Meditate on Śiva as Pañcamukha in the stated sequence (Sadyojāta onward, culminating in Īśāna), and integrate this with japa of Śiva-mantras (especially Pañcabrahma-related mantras and the Panchākṣarī) during daily worship or Mahāśivarātri observance.
