Observe your own body. It breathes.
You breathe when you are asleep, when you are no longer conscious of your own ideas of self-identity.
Who, then, is breathing?
The collection of information that you mistakenly think is you is not the protagonist in this drama called the breath. In fact, you are not breathing; breath is naturally happening to you.
You can purposely end your own life, but you cannot purposely keep your own life going. The expression, 'my life' is actually an oxymoron, a result of ignorance and mistaken assumption.
You don't possess life; life expresses itself through you.
Your body is a flower that life let bloom, a phenomenon created by life.
