Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 19

Sanskrit:

इत्युक्त्वैकेन हस्तेन कृत्वा गोवर्धनाचलम् । दधार लीलया विष्णुश्छत्राकमिव बालक: ॥ १९ ॥

ITRANS:

ity uktvaikena hastenakṛtvā govardhanācalamdadhāra līlayā viṣṇuśchatrākam iva bālakaḥ

Translation:

Having said this, Lord Kṛṣṇa, who is Viṣṇu Himself, picked up Govardhana Hill with one hand and held it aloft just as easily as a child holds up a mushroom.

Purport:

It is confirmed in the Hari-vaṁśa that Śrī Kṛṣṇa picked up the Govardhana Mountain with His left hand: sa dhṛtaḥ saṅgato meghair giriḥ savyena pāṇinā. “With His left hand He picked up that mountain, which was touching the clouds.” According to Śrīla Viśvanātha Cakravartī Ṭhākura, when Lord Kṛṣṇa was preparing to lift Govardhana Hill, a partial expansion of His Yoga-māyā potency named Saṁhārikī temporarily removed all the rain from the sky so that as He ran very swiftly from the porch of His house to the mountain, neither His turban nor other garments became wet.
