Śrīmad-Bhāgavatam · Text 10.21.16
Who is speaking and story frame
दृष्ट्वातपे व्रजपशून् सह रामगोपै:
सञ्चारयन्तमनु वेणुमुदीरयन्तम् ।
प्रेमप्रवृद्ध उदित: कुसुमावलीभि:
सख्युर्व्यधात् स्ववपुषाम्बुद आतपत्रम् ॥ १६ ॥
dṛṣṭvātape vraja-paśūn saha rāma-gopaiḥ
sañcārayantam anu veṇum udīrayantam
prema-pravṛddha uditaḥ kusumāvalībhiḥ
sakhyur vyadhāt sva-vapuṣāmbuda ātapatram
In the company of Balarāma and the cowherd boys, Lord Kṛṣṇa is continually vibrating His flute as He herds all the animals of Vraja, even under the full heat of the summer sun. Seeing this, the cloud in the sky has expanded himself out of love. He is rising high and constructing out of his own body, with its multitude of flower-like droplets of water, an umbrella for the sake of his friend.
