Osho My Samasati

When Breath Turns

If you stop your breath, the mind stops suddenly. If you stop your breath just now, your mind will stop suddenly; the mind cannot function. A sudden stoppage of breath and the mind stops. Why? Because they are disjoined. Only a moving breath is joined with the mind, with the body; a non-moving breath is disjoined.

The same happens when breath takes a turn. You are not joined with it. In that moment you can easily become aware of who you are.
