CC Antya 14.73, Translation and Purport:
"In the house of Kāśī Miśra, Śrī Caitanya Mahāprabhu would sometimes be greatly aggrieved, feeling separation from Kṛṣṇa. The joints of His transcendental body would slacken, and His arms and legs would become elongated. Rolling on the ground, the Lord would cry out in distress in a faltering voice and weep very sorrowfully. The appearance of Śrī Caitanya Mahāprabhu, awakening in my heart, maddens me."
This verse is Gaurāṅga-stava-kalpavṛkṣa 4.
