Atithi-prāpti and the Brāhmaṇa’s Deliberation on Triadic Dharma (अतिथिप्राप्तिः धर्मत्रयविचारश्च)
चतुष्पात् सकलो धर्मों भविष्यत्यत्र वै सुरा: । ततस्त्रेतायुगं नाम त्रयी यत्र भविष्यति,“देवताओ! इस सत्ययुगमें चारों चरणोंसे युक्त सम्पूर्ण धर्मका पालन होगा। तदनन्तर त्रेतायुग आयेगा, जिसमें वेदत्रयीका प्रचार होगा
catuṣpāt sakalo dharmo bhaviṣyaty atra vai surāḥ | tatas tretāyugaṃ nāma trayī yatra bhaviṣyati |
वैशम्पायन उवाच— “देवा:! अस्मिन् सत्ययुगे चतुष्पात् सकलो धर्मोऽत्र भविष्यति। ततः परं त्रेतायुगं नाम युगं भविष्यति, यत्र त्रयी (वेदत्रयी) प्रवर्तिष्यते।”
वैशम्पायन उवाच
The verse presents a yuga-based ethical framework: in Satya-yuga, dharma stands complete in all four parts, while in the subsequent Tretā-yuga the religious-ethical life is characterized by the prominence of the Veda-trayī. It implies that moral and spiritual conditions vary by cosmic age, and dharma’s fullness is not constant across time.
Vaiśampāyana is describing the succession of world-ages (yugas) to the gods, stating first the condition of Satya-yuga—where dharma is fully intact—and then announcing the coming of Tretā-yuga, marked by the spread and authority of the three Vedas.
