कृतयुगवर्णनम् तथा राजधर्मोपदेशः
Kṛtayuga Description and Instruction on Royal Dharma
तस्यापि द्विशती संध्या संध्यांशश्ष तथाविध: । द्वापरका मान दो हजार दिव्य वर्ष है तथा उतने ही सौ दिव्य वर्ष उसकी संध्या और संध्यांशके हैं (अत: सब मिलकर चौबीस सौ दिव्य वर्ष द्वापरके हैं)
tasya api dviśatī sandhyā sandhyāṁśaś ca tathāvidhaḥ |
Dijo Vaiśampāyana: Para ese (Dvāpara-yuga) también, el período crepuscular inicial (sandhyā) es de doscientos años divinos, y su porción crepuscular final (sandhyāṃśa) es de la misma medida. Así, el Dvāpara se entiende como de dos mil años divinos, con doscientos adicionales al comienzo y doscientos al final, sumando en total dos mil cuatrocientos años divinos.
वैशम्पायन उवाच
Educational Q&A
The verse teaches a structured view of cosmic time: each yuga has transitional periods (sandhyā and sandhyāṁśa) that frame its main duration, emphasizing that moral and cosmic orders change gradually rather than abruptly.
Vaiśampāyana is explaining yuga-chronology, specifying the length of Dvāpara-yuga along with its beginning and ending twilight intervals, as part of a broader account of time-cycles and the waxing and waning of dharma.
