Śrīmad-Bhāgavatam
Canto 10 Chapter 41 Text 1

śrī-śuka uvāca
stuvatas tasya bhagavān
darśayitvā jale vapuḥ
bhūyaḥ samāharat kṛṣṇo
naṭo nāṭyam ivātmanaḥ

TRANSLATION
Śukadeva Gosvāmī said: While Akrūra was still offering prayers, the Supreme Lord Kṛṣṇa withdrew His form that He had revealed in the water, just as an actor winds up his performance.
