CC Ādi 17.232
preme nṛtya kare, haila vaiṣṇava āgala
Saying “I have seen! I have seen!” and dancing in ecstatic love as though mad, he became a first-class Vaiṣṇava.
There was a Muslim tailor near the house of Śrīvāsa Ṭhākura who used to sew the garments of the family. One day he was very pleased with the dancing of Śrī Caitanya Mahāprabhu; indeed, he was enchanted. The Lord, understanding his attitude, showed him His original form as Kṛṣṇa. The tailor then began to dance, saying, “I have seen! I have seen!” He became absorbed in ecstatic love and began to dance with Lord Caitanya. Thus he became one of the foremost Vaiṣṇava adherents of Śrī Caitanya Mahāprabhu.
