Adhyaya 40: Kali-yuga Lakshana, Yuga-sandhyamsha, and the Re-emergence of Dharma
पञ्चविंशत्परिमिता न न्यूना नाधिकास् तथा तथा कल्पा युगैः सार्धं भवन्ति सह लक्षणैः
pañcaviṃśatparimitā na nyūnā nādhikās tathā tathā kalpā yugaiḥ sārdhaṃ bhavanti saha lakṣaṇaiḥ
تُقاس الكَلْبَات بخمسٍ وعشرين: لا أقلّ ولا أكثر. وعلى هذا النحو تقع مع اليوغات، وكلُّ يوغا مصحوبةٌ بسماتها وعلاماتها المميِّزة.
Suta Goswami
It frames Linga worship within cosmic time: Kalpas and Yugas unfold with fixed measures and signs, so Shaiva rites are understood as timeless disciplines adapted to the marks (lakṣaṇas) of each age under Shiva’s lordship as Pati.
By implying an ordered recurrence of Kalpas and Yugas with defining laws, it points to Shiva-tattva as the sovereign regulator (Pati) of cosmic cycles—time and its characteristics operate under His governance even as souls (paśu) traverse bondage (pāśa).
No single rite is named; the takeaway is Yuga-appropriate sādhanā—Pashupata-oriented discipline and Shiva-puja performed in harmony with the dharma and lakṣaṇas of the prevailing Yuga.
