Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
युगमानं स्मृतं विप्र खचतुष्करदार्णवाः । तद्दशांशास्तु चत्वारः कृताख्यं पादमुच्यते ॥ ६१ ॥
yugamānaṃ smṛtaṃ vipra khacatuṣkaradārṇavāḥ | taddaśāṃśāstu catvāraḥ kṛtākhyaṃ pādamucyate || 61 ||

Sanatkumara (teaching Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It frames human dharma and spiritual practice within cosmic time: the Kṛta Yuga is presented as the largest and most complete portion, implying maximal dharma and clarity of spiritual realization in that age.
Indirectly, it sets the background for why practices differ by age: as the yuga portions change, dharma’s strength changes—later teachings typically emphasize accessible disciplines (often bhakti) suitable for declining capacities.
It highlights kāla-nirṇaya (time determination) using bhūta-saṅkhyā (word-numeral encoding), a technical method used in traditional Sanskrit scientific and calendrical computations.
