śrī-bhagavān uvāca brahmaṁs te ’nugrahārthāya samprāptān viddhy amūn munīn sañcaranti mayā lokān punantaḥ pāda-reṇubhiḥ
至上主说道：“婆罗门啊，当知这些大圣贤来此只是为赐福于你。他们与我同游诸界，以其足尘净化一切。”
Śrīla Śrīdhara Svāmī explains that Lord Kṛṣṇa thought Śrutadeva had shown too much reverence to Him and not enough to the sages, and thus He turned the brāhmaṇa’s attention to them.
