Adhyaya 61 — ग्रह-नक्षत्र-स्थाननिर्णयः
Cosmic Abodes of Luminaries and the Shaiva Order of Time
उद्धृत्य पृथिवीछायां निर्मितां मण्डलाकृतिम् स्वर्भानोस्तु बृहत्स्थानं तृतीयं यत्तमोमयम्
uddhṛtya pṛthivīchāyāṃ nirmitāṃ maṇḍalākṛtim svarbhānostu bṛhatsthānaṃ tṛtīyaṃ yattamomayam
إذ يُستخرج ظلُّ الأرض مُصاغًا على هيئة قرصٍ دائريّ، يُقال إن هناك يقوم مُلكُ سْوَرْبْهانو الواسع: الإقليمُ الثالث، المؤلَّفُ من الظلمة.
Suta Goswami (narrating cosmological doctrine to the sages of Naimisharanya)
By mapping a “region of darkness” (tamomaya) within creation, the verse implicitly points to why Shiva as Pati is worshipped through the Linga: to transcend tamas (obscuration) and move the pashu (soul) toward clarity and liberation.
Shiva-tattva is suggested by contrast: even the vast tamasic domain (Svarbhānu’s region) is a created order within the cosmos, whereas Shiva as Pati is the transcendent ground beyond the guṇas (including tamas) who enables the soul to overcome obscuration.
No direct puja-vidhi is stated, but the teaching supports Pāśupata-oriented practice: reducing tamas through discipline, purity, mantra-japa, and Shiva-Linga upāsanā aimed at loosening pāśa (bondage) caused by ignorance.
