Adhyaya 8: Yogasthanas, Ashtanga Yoga, Pranayama-Siddhi, and Shiva-Dhyana leading to Samadhi
द्विदले षोडशारे वा द्वादशारे क्रमेण तु दशारे वा षडस्रे वा चतुरस्रे स्मरेच्छिवम्
dvidale ṣoḍaśāre vā dvādaśāre krameṇa tu daśāre vā ṣaḍasre vā caturasre smarecchivam
In a two-petalled lotus, or in a wheel of sixteen spokes, or in due order in one of twelve; again in one of ten spokes, or in a six-cornered or four-cornered maṇḍala—there one should contemplate Lord Śiva as Pati, the One who loosens the pāśa that bind the paśu.
Suta Goswami (narrating Shiva-dhyana/puja-vidhi taught in the Linga Purana tradition)
It authorizes yantra/mandala-based smaraṇa (contemplation) as a valid mode of Śiva-upāsanā, showing that Linga worship includes inner visualization of Śiva within sacred geometric forms.
Śiva is the meditated Reality (Pati) who is present to awareness through ordered forms; the verse implies that form (yantra) is a support for realizing the formless Lord who releases the paśu from pāśa.
Dhyāna with yantra-support—visualizing Śiva in lotus/chakra/mandala patterns (two-petalled, 16/12/10-spoked, hexagonal, or square)—a contemplative method aligned with Pāśupata-oriented Śiva smaraṇa.
