In plain words
The poet, of the cowherds' joy at the birth: When Kaṇṇaṉ of Tirukkōṭṭiyūr, ringed by lovely mansions, Kēśava of the beautiful locks, perfect in every auspicious quality, was born in the sweet house [of Nandagōpa], the people [of Āyppāṭi] sprayed oil and turmeric powder at one another, face to face, and with the two mingling, Kaṇṇaṉ's courtyard became one mire.
