“When the milk and curd are kept high on a swing hanging from the ceiling and Kṛṣṇa and Balarāma cannot reach it, They arrange to reach it by piling up various planks and turning upside down the mortar for grinding spices. Being quite aware of the contents of a pot, They poke holes in it. While the elderly gopīs go about their household affairs, Kṛṣṇa and Balarāma sometimes go into a dark room, brightening the place with the valuable jewels and ornaments on Their bodies and taking advantage of this light by stealing.
