“…Don’t try to put out fire by throwing on more fire. Don’t wash a wound with blood.
No matter how fast you run, your shadow keeps up. Sometimes it’s in front. Only full overhead sun diminishes your shadow. But that shadow has been serving you.
What hurts you, blesses you. Darkness is your candle. Your boundaries are your quest…
You must have shadow and light source both. Listen, and lay your head under the tree of awe…” ~Rumi

If you desire to lose your shadow, do not try to outrun it, but rather simply step into the shade.
