Adhyaya 4: अहोरात्र-युग-मन्वन्तर-कल्पमान तथा प्रलयान्ते सृष्ट्युपक्रमः
षष्टिश्चैव सहस्राणि कालः कलियुगस्य तु एवं चतुर्युगः काल ऋते संध्यांशकात्स्मृतः
ṣaṣṭiścaiva sahasrāṇi kālaḥ kaliyugasya tu evaṃ caturyugaḥ kāla ṛte saṃdhyāṃśakātsmṛtaḥ
A duração do Kali‑yuga é dita como sessenta mil anos. Do mesmo modo, recorda-se a duração de um ciclo de quatro eras (caturyuga)—excluindo as porções crepusculares (saṃdhyā‑aṃśas) que marcam as junções dos yugas.
Suta Goswami (narrating to the sages of Naimisharanya)
By defining yuga-time and the junctional saṃdhyā portions, the verse frames when dharma wanes and why steadfast Shiva-bhakti and Linga-upāsanā are emphasized as stabilizing disciplines for the pashu (soul) under changing kāla.
Though not naming Shiva explicitly, the teaching presumes kāla (cosmic time) as an ordered principle within the Lord’s governance—Shiva as Pati stands beyond measurement while regulating yuga-cycles that bind the pashu through pasha (limitations).
No single rite is prescribed in this line, but the implication for Kali Yuga is intensified reliance on Shiva-centered sādhanā—Linga-pūjā, mantra-japa, and Pāśupata-oriented discipline to transcend kāla-bound agitation.
