युगधर्मवर्णनम् — चतुर्युग, गुण, धर्मपाद, तथा वार्तोत्पत्ति
चतुर्भागैकहीनं तु त्रेतायुगमनुत्तमम् कृतार्धं द्वापरं विद्धि तदर्धं तिष्यमुच्यते
caturbhāgaikahīnaṃ tu tretāyugamanuttamam kṛtārdhaṃ dvāparaṃ viddhi tadardhaṃ tiṣyamucyate
উত্তম ত্রেতাযুগ কৃতযুগের তুলনায় এক পাদ কম বলা হয়। দ্বাপরকে কৃতের অর্ধেক জেনো; আর তার অর্ধেকই তিষ্য (কলি) নামে খ্যাত।
Suta Goswami
By defining the diminishing strength of the yugas, the verse frames why Shiva-upāsanā and Linga-pūjā become especially vital in later ages, when dharma and inner steadiness decline and the Pashu needs stronger support to turn toward Pati.
Though the verse speaks of kāla (yuga-measures), it implicitly contrasts changing time with Shiva as Pati—unchanging, transcendent to yugas—toward whom the bound soul (Pashu) must orient for release from pāśa.
No single rite is prescribed here; the takeaway is yuga-based urgency: in Tiṣya/Kali, disciplined Pāśupata-oriented sādhana—japa, pūjā, and inner detachment from pāśa—becomes the practical means to stabilize the mind and seek Shiva.
