Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 1

Sanskrit:

श्रीशुक उवाचगोवर्धने धृते शैले आसाराद् रक्षिते व्रजे । गोलोकादाव्रजत्कृष्णं सुरभि: शक्र एव च ॥ १ ॥

ITRANS:

śrī-śuka uvācagovardhane dhṛte śaileāsārād rakṣite vrajego-lokād āvrajat kṛṣṇaṁsurabhiḥ śakra eva ca

Translation:

Śukadeva Gosvāmī said: After Kṛṣṇa had lifted Govardhana Hill and thus protected the inhabitants of Vraja from the terrible rainfall, Surabhi, the mother of the cows, came from her planet to see Kṛṣṇa. She was accompanied by Indra.

Purport:

The word go-lokāt here indicates the material planet called Goloka which is filled with exceptional cows. Surabhi went joyfully to see Lord Kṛṣṇa, but Indra went fearfully. As indicated by this verse, Lord Kṛṣṇa had to adopt extraordinary measures to protect His Vṛndāvana associates from Indra’s obnoxious and offensive attack. Certainly Indra was ashamed, and also nervous about his future. Having acted improperly, he had fearfully gone to seek the shelter of Lord Brahmā, who then ordered him to take along Surabhi from the material Goloka planet and go to see Kṛṣṇa.
