Legend of Hot Milk

The immeasurable love of Krishna for Radha made Krishna's wives jealous of Radha. Once, they all planned a mischief to make Radha suffer. They set out a bowl of burning hot milk. They gave the bowl to Radha, saying that Krishna had sent it for her. Radha readily drank the hot milk.

When the wives returned to Krishna, they found him full of painful ulcers. This shows that Krishna resides in every pore of Radha i.e. why the hot milk didn't touch Radha, but it affected Krishna. He took all her pain and miseries upon himself.
