युगधर्मवर्णनम् — चतुर्युग, गुण, धर्मपाद, तथा वार्तोत्पत्ति
एषा रजस्तमोयुक्ता वृत्तिर् वै द्वापरे स्मृता आद्ये कृते तु धर्मो ऽस्ति स त्रेतायां प्रवर्तते
eṣā rajastamoyuktā vṛttir vai dvāpare smṛtā ādye kṛte tu dharmo 'sti sa tretāyāṃ pravartate
អាកប្បកិរិយានេះ ដែលភ្ជាប់ជាមួយ រាជស និង តមស ត្រូវបានចងចាំថា ជាលក្ខណៈនៃសម័យទ្វាបរ។ តែក្នុងសម័យដំបូង គ្រឹត ធម៌មានស្ថិតពិតប្រាកដ; ហើយធម៌នោះឯង បន្តដំណើរទៅកាន់សម័យ ត្រេតា។
Suta Goswami (narrating to the sages of Naimisharanya)
By linking yuga-conduct to rajas and tamas, the verse implies why Shiva-Linga worship and Shaiva sadhana are needed in later yugas: to purify the guṇas of the pashu (bound soul) and re-establish dharma through devotion and discipline.
Implicitly, Shiva-tattva stands as Pati beyond the guṇas; when beings fall into rajasic-tamasic conduct, turning to Shiva (the transcendent Lord) becomes the means to regain dharmic alignment and loosen pasha (bondage).
Guṇa-śuddhi is the takeaway: Pāśupata-oriented discipline—japa, vrata, and Linga-pūjā with inner restraint—aims to overcome rajas and tamas so dharma can manifest even in declining yugas.
