This is one of my favorite concepts from Tolle. To me, it speaks of the deliberateness of faith and understanding the Love of God (or simply the love of Life, if a person doesn't believe in God, per se). It's an acceptance of the purpose in life, in knowing that this isn't a random world with chaos and accidents. I guess, to me, this is part of the definition of faith: believing (knowing) that each event, each moment in life comes with a meaning and a reason to me, personally.
When I can remember this, peace comes.
Here's to a peaceful and right day of moments for you!
