Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 25
देवे वर्षति यज्ञविप्लवरुषा वज्राश्मवर्षानिलै:सीदत्पालपशुस्त्रियात्मशरणं दृष्ट्वानुकम्प्युत्स्मयन् । उत्पाट्यैककरेण शैलमबलो लीलोच्छिलीन्ध्रं यथाबिभ्रद् गोष्ठमपान्महेन्द्रमदभित् प्रीयान्न इन्द्रो गवाम् ॥ २५ ॥

Indra became angry when his sacrifice was disrupted, and thus he caused rain and hail to fall on Gokula, accompanied by lightning and powerful winds, all of which brought great suffering to the cowherds, animals and women there. When Lord Kṛṣṇa, who is by nature always compassionate, saw the condition of those who had only Him as their shelter, He smiled broadly and lifted Govardhana Hill with one hand, just as a small child picks up a mushroom to play with it. Holding up the hill, He protected the cowherd community. May He, Govinda, the Lord of the cows and the destroyer of Indra’s false pride, be pleased with us.
The word indra means “lord” or “king.” Thus in this verse Kṛṣṇa is pointedly called indro gavām, “the Lord of the cows.” In fact, He is the real Indra, the real ruler, of everyone, and the demigods are merely His servants, representing His supreme will. It is apparent from this and the previous verses in this chapter that Lord Kṛṣṇa’s lifting of Govardhana Hill made quite an impression on the simple cowherd men of Vṛndāvana, and they repeatedly remembered this feat. Certainly anyone who soberly and objectively considers the activities of young Kṛṣṇa will surrender to Him and become His eternal devotee in loving devotional service. That is the rational conclusion one should come to after reading this chapter.
