You have 2 parts. Yourself & your shadow. Your shadow is a mere reflection of you. You yourself are the real self.
When the sun is shining, the shadow could be in any part of you. It could be front, back, sideways, or horizontal.
If you look at it figuratively, the right place for the shadow to be is behind you. Because you are the leader, & the shadow is the follower.
In life, we need to be brave. When the sun is shining in full fury, we need to be able to face the sun, be brave, & take risks. The one who faces the sun bravely assumes position of leadership. Then it’s followers in the form of its shadow follow behind you. Leaders face the sun.
Turn your face to the sun & the shadow will fall behind you !
