There’s only so much we can do to physically change the world at any given time. It takes a moment on any average day to change our minds, when we know how.
The secret to being at peace in this world is accepting life as it comes and responding advantageously. Meditation tunes our awareness, rewiring our instincts to make the right decision, at the right time, for the right reasons.
Trying to change the circumstances of life is like trying to change the colour of the sky. In the grand scheme, you can’t.
Trying to get more good and less bad is like hitting the shoreline with a shovel thinking you’ll change the direction of the tides.
But you can always change your approach to life - your attitude about the sky as it happens to be.
