Sitting by a small cave the other day and humming, I noticed that I doubled my humming effort with the help of the echo.
And realized: “we have to empty ourselves so as to resonate (with What Is).”
We can be full of ourselves or we can be full of reality.
Mindfulness is not about fullness of mind: a mind full of itself is closed off to input.
Mindfulness is about being full of Reality: to make that happen, empty yourself out (to resonate with What Is).
