In chapter 7, Krishna starts to explain who he really is. He uses a beautiful picture: a necklace of pearls.

When you look at a pearl necklace, you see the pearls. You don't see the string. But the string runs through every pearl and holds the whole necklace together. Without it, the pearls would scatter on the floor.

Krishna says he is like that string. Everything in the world, every person, animal, tree and star, is like a pearl. And he is the hidden string running through all of them, holding them together.

This is a key idea in Hindu thought. God is not only far away in the sky. God is also inside everything, quietly holding it together, even when we can't see it.

This changes how we can look at the world. The tree outside your window, the stranger at the store and your annoying younger brother are all on the same string.

You don't have to see the string to trust it is there. Just remember the necklace when the world feels like it's falling apart.
