|Canto 10: The Summum Bonum||Chapter 27: Lord Indra and Mother Surabhi Offer Prayers|
Bhaktivedanta VedaBase: Śrīmad Bhāgavatam 10.27.19
kṛṣṇa kṛṣṇa mahā-yogin
sa-nāthā vayam acyuta
surabhiḥ uvāca — Surabhi said; kṛṣṇa kṛṣṇa — O Kṛṣṇa, Kṛṣṇa; mahā yogin — O greatest of mystics; viśva-ātman — O Soul of the universe; viśva-sambhava — O origin of the universe; bhavatā — by You; loka nāthena — the master of the world; sa-nāthāḥ — having a master; vayam — we; acyuta — O infallible one.
Mother Surabhi said: O Kṛṣṇa, Kṛṣṇa, greatest of mystics! O Soul and origin of the universe! You are the master of the world, and by Your grace, O infallible Lord, we have You as our master.
Śrīla Viśvanātha Cakravartī Ṭhākura points out here that mother Surabhi is feeling great ecstasy as she repeats the words "Kṛṣṇa, Kṛṣṇa." Kṛṣṇa lifted Govardhana Hill by His mystic power and thus protected the cows of Vṛndāvana, whereas her so-called master, Indra, had tried to kill them. Thus Surabhi now clearly understands that it is not the demigods but rather the Supreme God, Kṛṣṇa Himself, who is her real master forever.
