kva kṛṣṇaḥ śrī-niketanaḥ
brahma-bandhur iti smāhaṁ
kva — who; aham — I; daridraḥ — poor; pāpīyān — sinful; kva — who; kṛṣṇaḥ — the Supreme Personality of Godhead; śrī-niketanaḥ — the transcendental form of all opulence; brahma-bandhuḥ — the friend of a brāhmaṇa, not fit even to be called a brāhmaṇa; iti — thus; sma — certainly; aham — I; bāhubhyām — by the arms; parirambhitaḥ — embraced.
He said, “ ‘Who am I? A sinful, poor friend of a brāhmaṇa. And who is Kṛṣṇa? The Supreme Personality of Godhead, full in six opulences. Nonetheless, He has embraced me with His two arms.’ ”
This verse was spoken by Sudāmā Brāhmaṇa in Śrīmad-Bhāgavatam (10.81.16), in connection with his meeting Lord Kṛṣṇa.
