हित्वा भाज्यंगभागादीन्कलीकृत्य खखाक्षिभिः । भजेद्वर्षाणि शेषे तु गुणिते द्वादशादिभिः ॥ १२८ ॥
hitvā bhājyaṃgabhāgādīnkalīkṛtya khakhākṣibhiḥ | bhajedvarṣāṇi śeṣe tu guṇite dvādaśādibhiḥ || 128 ||
Isantabi ang mga naunang yunit ng tagahati at mga bahaging may kapiraso, at gawing bilang ng Panahong Kali ang natira sa pamamagitan ng mga bilang na “kha-kha-akṣi”; saka kwentahin ang mga taon. Kung may natira pa, imultiply sa labindalawa at sa mga kaugnay na salik upang makuha ang mga panlahok na sukat.
Sanatkumara (in instruction to Narada, within a Vedanga-style technical passage)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It presents disciplined, rule-based time-reckoning as part of dharma: correct calendrical knowledge supports right observance of vows, rites, and sacred timings, which in turn stabilizes spiritual practice.
Indirectly: by teaching accurate computation of years and sub-units (months, etc.), it safeguards proper observance of vrata and worship-times—practical supports that sustain steady Vishnu-bhakti in daily life.
Jyotiṣa Vedāṅga (astronomy/astrology and calendrics): converting values into Kali-era counts, handling remainders, and scaling by twelve for subsidiary time divisions used in ritual scheduling.
