A Secret of Life is that Life is eternal (when seen beyond the ego), but always moving toward aging and death when ego clouds our view. Therefore, see with ego-less eyes! With ego-less eyes we are blind to the boundaries between us.
The ego, however, hangs on to "little life"; and may convince us of our near total separation from one another. Don't believe it. The eye of the needle may be small, but big mind can surrender into "big Life" - and it becomes mystically clear that "all is one".
