Every living thing, animal or human, or tree experiences that which is called death, with no exception. You've all accepted that one a long time ago. Spirit, which is who we really are, or Source, is eternal. So what death must be is a changing of the perspective of that Eternal Spirit. If I am standing in my physical body and am consciously connected to that Eternal Spirit, then I'm Eternal in nature and I need not ever again fear any endedness, because, from that perspective I understand that there is not any of that.
Cats do what cats do, ducks do what ducks do, and eagles do what eagles, do. If you take a duck and ask it to do an eagles' job, shame on you. As a leader, your job is to help your ducks to become better ducks and your eagles better eagles - to put individuals in the right places and help them reach their potential.
