CC Antya 1.79, Translation and Purport:
"My dear friend, now I have met My very old and dear friend Kṛṣṇa on this field of Kurukṣetra. I am the same Rādhārāṇī, and now We are meeting together. It is very pleasant, but I would still like to go to the bank of the Yamunā beneath the trees of the forest there. I wish to hear the vibration of His sweet flute playing the fifth note within that forest of Vṛndāvana."
This is the verse composed by Śrīla Rūpa Gosvāmī. It is included in the Padyāvalī (387), an anthology of verses he compiled.
