प्रणवार्थ-शिवतत्त्व-निर्णयः
The Determination of Śiva as the Meaning of Praṇava
यो वै मुमुक्षुभिर्ध्येयः शम्भुराकाशमध्यगः । सर्वव्यापी प्रकाशात्मा भासरूपो हि चिन्मयः
yo vai mumukṣubhirdhyeyaḥ śambhurākāśamadhyagaḥ | sarvavyāpī prakāśātmā bhāsarūpo hi cinmayaḥ
Śambhu, abiding in the very midst of space, is indeed the One to be meditated upon by seekers of liberation. He is all-pervading; His essence is luminous awareness—truly, His form is radiance, for He is of the nature of pure Consciousness.
Suta Goswami (narrating the Kailasa Samhita teaching to the sages, summarizing the object of Śiva-meditation)
Tattva Level: pati
Shiva Form: Dakṣiṇāmūrti
It defines the mokṣa-oriented meditation object: Śambhu is not limited to a place or body, but is the all-pervading Conscious Light (cit-prakāśa). Liberation is approached by recognizing and contemplating Śiva as the inner, luminous reality that pervades all.
The Liṅga is a saguna support for dhyāna that points to Śiva’s nirguṇa truth described here—form as radiance and consciousness. Worship begins with a visible emblem (Liṅga) and matures into contemplation of the all-pervading Śiva-tattva.
A dhyāna practice: meditate on Śambhu as luminous awareness pervading ākāśa and all beings; support it with japa of the Pañcākṣarī (Om Namaḥ Śivāya) and, where traditional, Tripuṇḍra-bhasma and Rudrākṣa as aids to steadiness and Śiva-smaraṇa.
