Adhyaya 70: आदिसर्गः—महत्-अहङ्कार-तन्मात्रा-भूतसृष्टिः, ब्रह्माण्डावरणम्, प्रजासर्गः, त्रिमूर्ति-शैवाधिष्ठानम्
ते च प्रकाशबहुलास् तमःपृक्ता रजो ऽधिकाः तस्मात्ते दुःखबहुला भूयोभूयश् च कारिणः
te ca prakāśabahulās tamaḥpṛktā rajo 'dhikāḥ tasmātte duḥkhabahulā bhūyobhūyaś ca kāriṇaḥ
彼らは多くの光(サットヴァ)を含むが、闇(タマス)と混じり、しかも激情の動き(ラジャス)が優勢である。ゆえに苦が多く、行為を幾度も繰り返し、束縛の輪廻に回転する。
Suta Goswami (narrating the doctrinal teaching within the Purva-Bhaga context)
It frames why the pashu (bound soul) remains restless and sorrowful under rajas-tamas; Linga worship is directed to Pati (Shiva) as the luminous reality beyond the gunas, purifying the doer-sense and loosening pasha (bondage).
By contrast: beings are mixed and rajasic, hence bound to repeated action; Shiva-tattva is the pure prakāśa (conscious light) that is not compelled by rajas-tamas, and thus is the liberating Lord (Pati).
The takeaway aligns with Pashupata Yoga: reduce rajasic compulsion through discipline, mantra and Linga-upāsanā, and cultivate sattva as a stepping-stone to recognize Shiva as the transcendent light beyond all guna-driven agency.
