युगधर्मवर्णनम् — चतुर्युग, गुण, धर्मपाद, तथा वार्तोत्पत्ति
वर्तयन्ति स्म तेभ्यस्तास् त्रेतायुगमुखे प्रजाः ततः कालेन महता तासामेव विपर्ययात्
vartayanti sma tebhyastās tretāyugamukhe prajāḥ tataḥ kālena mahatā tāsāmeva viparyayāt
At the dawn of the Tretā-yuga, those progenitor beings set the generations in motion from them; but in the course of great time, through the very reversal of their own condition, that order declined.
Suta Goswami
It frames history as cyclical—when dharma reverses over time, refuge in Pati (Shiva) through Linga-upāsanā becomes the stabilizing means to realign prajā with sacred order.
By implying that worldly order rises and falls through time, it points to Shiva-tattva as the unchanging Pati beyond kāla, the ground by which the pashu can transcend viparyaya (reversal) and pasha (bondage).
No single rite is named, but the takeaway aligns with Pāśupata discipline: when decline sets in, one should return to Shiva-centered sādhanā—Linga-pūjā, japa, and inner steadiness to counter viparyaya.
