24.5.p141

The Bhagavān told him, “Last night, Śakra the Lord of the Gods knew that I wanted to wash my robes, so he created this bathing pool. I then had the thought, ‘Where will I lay out my robes to wash them?’ The four god kings knew that thought in my mind, and they brought me this stone. I also thought, ‘Where will I hang up these robes to dry?’ A tree spirit knew that thought in my mind, so it lowered this tree limb.”
