In plain words
Parted from Your wife, You told Your brother that the cool moonlight burned like the summer sun; and in Vṛndāvana You let the doe-eyed gopīs search for You until they were lost in You. Salutation to Nārāyaṇa.
Word for word
When parted from Your own wife, You told Your younger brother plainly that the cool moonlight was summer's burning heat; then in Vṛndāvana You made the doe-eyed women, searching for You, sink deep. Salutation to Nārāyaṇa.
