Depression is not the absence of light or an overwhelming surge of darkness. It is a blankness, a not seeing. It is a shelter from sight and from engagement in authentic experience, wherever such involvement settles on the gradient-scale of dualities: happy-sad; excited-bored; fearful-loving, etc.
Today I was saved from depression by shadows.
True, I had to make some effort of my own. For starters, I chose not to lie down in another room away from others. From the living room couch, reading beneath the Dig Dug orchestra, I happened to look up and see a new, living wall. Connecting to what was, these fluttering shadows, and the amazement that took hold, brought me back.
Here is my attempt to return the favor.
