Your body and your mind (are) the metabolizers of experiences in consciousness.
Many bodies and many minds exist in us: body of a child, teenager, baby.
Body and mind are constantly dying and being reborn.
Body and mind are only sensations.
They are discontinuous, intermittent.
Something so intermittent cannot be the real you.
Threads of desire, impulses of memory.
Memory is very unreliable as a form of identity.
Our true identity is the screen of consciousness in which these experiences come and go.
The onlooker is always there.
That is the real meaning of the phrase, in the ancient wisdom of (adanta? I don’t know this reference he makes, or how to spell it):
“I’m not in the body; the body is in me. I’m not in the mind; the mind is in me. I’m not in the world; the world is in me.”
