Adhyaya 8: Yogasthanas, Ashtanga Yoga, Pranayama-Siddhi, and Shiva-Dhyana leading to Samadhi
किंचिदुन्नामितशिर दन्तैर्दन्तान्न संस्पृशेत् सम्प्रेक्ष्य नासिकाग्रं स्वं दिशश्चानवलोकयन्
kiṃcidunnāmitaśira dantairdantānna saṃspṛśet samprekṣya nāsikāgraṃ svaṃ diśaścānavalokayan
डोके किंचित उंच ठेवावे; दातांनी दातांना स्पर्श करू नये. स्वतःच्या नासिकाग्रावर दृष्टी स्थिर करून, दिशांकडे पाहू नये.
Suta Goswami (narrating the Purana’s teaching on disciplined yogic posture and gaze)
It gives a practical meditative restraint—posture and gaze control—that stabilizes the mind and senses, making the worshipper fit for inner Linga-dhyana and focused devotion to Śiva as Pati.
Śiva-tattva is approached here not through speculation but through disciplined inwardness: when the pashu (soul) withdraws from outward directions and steadies attention, it becomes capable of contemplating the transcendent Lord beyond pasha (bondage).
A dhyāna-vidhi emphasizing pratyāhāra-like sense-withdrawal and ekāgratā (one-pointedness) by fixing the gaze at the nose tip and avoiding restless scanning of the quarters.
