Adhyaya 8: Yogasthanas, Ashtanga Yoga, Pranayama-Siddhi, and Shiva-Dhyana leading to Samadhi
समजानुस् तथा धीमान् एकजानुरथापिवा समं दृढासनो भूत्वा संहृत्य चरणावुभौ
samajānus tathā dhīmān ekajānurathāpivā samaṃ dṛḍhāsano bhūtvā saṃhṛtya caraṇāvubhau
ليجلس السالك الحكيم إمّا وركبتاه على مستوى واحد، أو مع رفع ركبةٍ واحدة؛ فإذا استقرّ في مقعدٍ ثابتٍ متوازن، فليضمّ القدمين ويهيّئهما—وبذلك يُقيم كبحَ الجسد سندًا للتأمّل المتوجّه إلى شيفا.
Suta Goswami (narrating Shiva-upasana/yoga discipline to the sages of Naimisharanya)
It prescribes the bodily steadiness (dṛḍhāsana) that makes linga-upāsanā effective—by restraining movement and gathering the limbs, the worshipper supports one-pointed attention toward Pati (Shiva).
Shiva-tattva is approached here as the supreme Pati realized through inner composure; when the pashu (individual self) reduces distraction and steadies the body, the mind becomes fit to turn toward Shiva’s presence.
Āsana-siddhi: sitting in a balanced, firm posture (either both knees level or one-knee posture) and withdrawing/placing the feet properly—preparatory discipline aligned with Pashupata-style meditation and puja.
