What is it..? Definitions refer to illusion in what our senses report.. Einstein astounds us of persistent illusion in the world we see.. But..we ask..how can that be..? There are things out there not to be denied..! We must now turn to that perennial truth which leads us to the subjective realm.. We need examine the assumption of I in: I see the train smoking and chugging and soon departing around the bend.. Does I also move around that bend..? An obvious question which is never asked..! That train..it is assumed smokes and chugs unstrung from I.. But looking again the truth arrives: I know only a train appearing passing through I.. A new I is born arriving with joy...
