In that palace the learned brāhmaṇa saw the Lord of the Sātvatas, Śrī Kṛṣṇa, together with His wife, who fanned Him with a gold-handled yak-tail fan. She personally served Him in this way, even though she was constantly attended by a thousand maidservants equal to her in personal character, beauty, youth and fine dress.
