In Satya-yuga, Lord Nārāyaṇa was worshiped by meditation ( kṛte yad dhyāyato viṣṇum ). Indeed, everyone always meditated upon Lord Viṣṇu, Nārāyaṇa, and achieved every success by this process of meditation. In the next yuga, Tretā-yuga, the performance of yajṣa began ( tretāyāṁ yajato mukhaiḥ ). Therefore this verse says, trayī tretā-mukhe. Ritualistic ceremonies are generally called fruitive activities. Śrīla Viśvanātha Cakravartī Ṭhākura says that in Tretā-yuga, beginning in the Svāyambhuva-manvantara, ritualistic fruitive activities were similarly manifested from Priyavrata, etc.

Thus end the Bhaktivedanta purports of the Ninth Canto, Fourteenth Chapter, of the Śrīmad-Bhāgavatam, entitled “King Purūravā Enchanted by Urvaśī.”
