The wind doesn’t have a physical body, nor does the lightning or thunder, yet they are completely real. There is a serene intelligence inside you that exists in and of itself, independent of matter, always joyous and free. Sometimes it puts on a physical body. But when it directs its mind, like a divine eye, back onto itself, it recognizes itself as unborn, undying awareness. You are not your body, Indra, any more than you are the coat or shirt you have also put on. You are that pure, tranquil, non-material intelligence itself.
— Chhandogya Upanishad
