See the light, walk into the light, be grateful for the light, look for the light.
There's a reason so many of our metaphors regarding hope and encouragement, wisdom and mastery have to do with light. We identify with it as creatures-on-a-journey; it is our guide (both literally and figuratively), our protector, and our source of and for life.
So, it's a nice idea, when struck by indecision, fatigue, disappointment, or shattered illusions, to think about becoming reunited by and with it. It is our teacher and the amazing thing is, it's always there. And if it disappears for a while? You know it has to come back.
Some universal laws are unquestionable.
There is great comfort in that.
Now. Go be light.
