Adhyaya 4: अहोरात्र-युग-मन्वन्तर-कल्पमान तथा प्रलयान्ते सृष्ट्युपक्रमः
त्रेताद्वापरतिष्याणां कृतस्य कथयामि वः निमेषपञ्चदशका काष्ठा स्वस्थस्य सुव्रताः
tretādvāparatiṣyāṇāṃ kṛtasya kathayāmi vaḥ nimeṣapañcadaśakā kāṣṭhā svasthasya suvratāḥ
I shall explain to you the time-measures of the Tretā, Dvāpara, and Kali ages, and also of the Kṛta age. O you of good vows, for one in a normal, steady state, a kāṣṭhā consists of fifteen nimeṣas.
Suta Goswami (narrating to the sages of Naimisharanya)
It establishes the Purāṇic framework of kāla (time) within which all rites—such as linga-pūjā, vrata, and dīkṣā—are performed; Shiva as Pati is understood as the Lord who transcends these time-measures while regulating them for the pashu’s disciplined practice.
By defining measurable time for embodied beings, it indirectly points to Shiva-tattva as Kāla-niyantā (the regulator of time) and yet Kāla-atīta (beyond time), the Pati who governs cosmic cycles without being bound by them like the pashu under pāśa.
Vrata-based discipline and measured observance (kāla-niyama) are implied—timely japa, pūjā, and yogic steadiness (svastha) that support Pāśupata-oriented regulation of body and mind.
