कृतयुगवर्णनम् तथा राजधर्मोपदेशः
Kṛtayuga Description and Instruction on Royal Dharma
तस्य वर्षशतं संधि: संध्यांशश्व॒ ततः परम् | संधिसंध्यांशयोस्तुल्यं प्रमाणमुपधारय
tasya varṣaśataṁ sandhiḥ sandhyāṁśaś ca tataḥ param | sandhi-sandhyāṁśayor tulyaṁ pramāṇam upadhāraya ||
Vaiśampāyana dit : « Pour cet âge, la période de transition (sandhi) est de cent ans, et ensuite la portion finale de transition (sandhyāṁśa) est elle aussi de cent. Comprends que la mesure du sandhi et du sandhyāṁśa est égale. »
वैशम्पायन उवाच
The verse defines a rule for yuga chronology: the transitional period (sandhi) and the concluding transitional portion (sandhyāṁśa) are of equal duration—each stated here as one hundred years for the age being described.
Vaiśampāyana is explaining the measured structure of an age (yuga), specifying how long its junction-periods last and instructing the listener to treat the sandhi and sandhyāṁśa as equal in length.
