It's summer. It's warm enough to stand outside and stargaze. Even in the hazy urban sky, there are stars. Constant. Distant. Light in the dark.
A lodestar is a star that can be used for navigating; a point of reference so true that you can use it to find out where you are and to get where you are going. You can only use it at night, when the world is dark and your normal points of reference are hard to see. You can only use it because you have studied it and made it familiar.
Go outside tonight as the sun goes down and it begins to get dark. Practice knowing that darkness brings its own way of clearing out noise and haziness. Practice knowing that you will find your lodestar in the dark.
