"The blue sky takes place outside you, but the experience of joy you get from the blue sky takes place inside you."

As Andrew Klavan says,

The blue sky takes place outside you, but the experience of joy you get from the blue sky takes place inside you. You start to think about the existence of God and God's creation. Paying attention and love are very closely related. When you live life fully awake and alert, you are full of joy and vitality.
