CC Antya-lila

As an independent leader among elephants enters the water with its female elephants, Kṛṣṇa, who is transcendental to the Vedic principles of morality, entered the water of the Yamunā with the gopīs. His chest had brushed against their breasts, crushing His flower garland and coloring it with red kuṅkuma powder.

CC Antya 18.25, Translation and Purport:

"As an independent leader among elephants enters the water with its female elephants, Kṛṣṇa, who is transcendental to the Vedic principles of morality, entered the water of the Yamunā with the gopīs. His chest had brushed against their breasts, crushing His flower garland and coloring it with red kuṅkuma powder. Attracted by the fragrance of that garland, humming bumblebees followed Kṛṣṇa like celestial beings of Gandharvaloka. In this way, Lord Kṛṣṇa mitigated the fatigue of the rāsa dance."

This verse is from Śrīmad-Bhāgavatam (10.33.22).
