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
Con la cabeza ligeramente elevada, no permita que los dientes se toquen. Fijando la mirada en la punta de su propia nariz, no mire hacia las direcciones—para aquietar los sentidos en la contemplación śaiva del Pati (el Señor 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.
