युगधर्मवर्णनम् — चतुर्युग, गुण, धर्मपाद, तथा वार्तोत्पत्ति
चतुर्भागैकहीनं तु त्रेतायुगमनुत्तमम् कृतार्धं द्वापरं विद्धि तदर्धं तिष्यमुच्यते
caturbhāgaikahīnaṃ tu tretāyugamanuttamam kṛtārdhaṃ dvāparaṃ viddhi tadardhaṃ tiṣyamucyate
ويُقال إنّ تريتَا-يوغا، وهو أرفع العصور، قد نَقَصَ رُبعًا (قياسًا إلى كِرتا). واعلم أنّ دْفابَرا-يوغا هو نصف كِرتا-يوغا؛ ونصف ذلك (الدْفابَرا) يُسمّى تِصْيَة (كالي).

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.
