You Are That
You are that. The statement is frequently repeated in the sixth chapter of the Chandogya Upanishad (c. 800-600 BCE) as the teacher Uddalaka Aruni instructs his son in the nature of brahman, the supreme reality.
Leaves are alive while being part of their tree, of their bigger entity. Then they fall and fade away. And no one remembers them anymore. The same happens with people. Leaves are only a small part of the manifestation of life. We are just a frail manifestation of the world. But we are that world. You are that.
You can be a leaf, seed, or stone. Each photograph represents the last testimony of a different natural object, after which it disappears forever. What we actually see is Eternity.
