This is a quotation from Śrīmad-Bhāgavatam (10.21.19). As Kṛṣṇa wandered in the forest with Baladeva and the two of Them wonderfully played Their flutes, all the gopīs became very much attracted. Thus they praised the Lord’s activities, describing how He was enthusing all the plants, birds, hills, water — everything.
