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
With the head slightly raised, he should not let the teeth touch. Fixing his gaze on the tip of his own nose, he should not look about in the directions—thus steadying the senses for Śaiva contemplation of the Pati, Lord Śiva.
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.
