Shadows of Turning

One shadow. Two shadows.. Three shadows... And two remain when the third one fades, Until the light is directly behind me. And then there's just one. As I move further away, a second and third one Is cast from the light just ahead, And one of the three disappears As the other joins the one behind me, Like an off-centered aura; And when I walk from whence I came There is my shadow and its aura in front of me, Mimicking my every movement, until they join as one. Then two others appear as I near a light, The two at my side are strong, As the one in front flickers away, So goes the one at my left side; And the one behind, alone, slowly walks ahead of me. Almost simultaneously disappearing, Until the shadow with an aura appears And move around from back to left to front; And so goes the cycle as I move from light to light, Until I see only one shadow, Which slowly fades as I turn to go left, Then a lighter one angles long and leftward, Disappearing quickly as the two reappear At an angle behind me, to my left, then a bit ahead Until I turn left again and rest beside the column, And there I rest just me and my shadows.
