अध्याय 91: अरिष्ट-लक्षण, मृत्यु-संस्कार, पाशुपत-धारणा तथा ओङ्कार-उपासना
उदङ्मुखः प्राङ्मुखो वा स्वस्थश् चाचान्त एव च स्वस्तिकेनोपविष्टस्तु नमस्कृत्वा महेश्वरम्
udaṅmukhaḥ prāṅmukho vā svasthaś cācānta eva ca svastikenopaviṣṭastu namaskṛtvā maheśvaram
Facing north or east, composed in body and having performed ācamana, one should sit in the svastika posture; then, after bowing, offer reverent homage to Mahēśvara—Pati, Śiva, the Lord who loosens the pāśas that bind the paśu (the soul).
Suta Goswami (narrating Shiva-puja procedure to the sages of Naimisharanya)
It sets the practitioner’s ritual readiness—proper direction, ācamana (purificatory sipping), stable seated posture, and namaskāra—before beginning Linga-Puja, emphasizing inner steadiness and reverence to Mahēśvara.
By directing worship to Mahēśvara, it points to Shiva as Pati (the Supreme Lord), the one worthy of surrender and the remover of pāśas (bondages) that bind the paśu (individual soul).
Ācamana for purification and sitting in svastika-āsana (a steady meditative posture), aligning puja with yogic composure central to Shaiva/Pāśupata discipline.
