What is the self?
It is said that “this life is all” and that you (like everyone else) are going to die, and when you do, that’s it. If your self is your individual self, and you have never known a valid sense of we, (let alone anything more inclusive), then no, there’s no cosmic justice and yes, you’re going to die.
It is also said, in various ways both poetic and prosaic, that
• you and I are the same, or are expressions of the same, and that our separateness is not a separateness of different beings, but of different lives that the same being experiences; or
• all spiritual growth is about transcending the merely individual and “thinking globally” (and caring globally) even as you continue to live and act locally; or
• everyone is God in disguise, and our lives are like books being read by a voracious reader; when God finishes one book God puts it back on the shelf and starts another, and all of the books get read in due course; or
• while you were taught that the universe started with the Big Bang some 12-15 billion years ago and a subsequent chain of cause-and-effect resulted in stars settling out, planets cooling, life originating and evolving on many of them, and you as an individual being born to one species thereof, the truth of the matter is that some 12-15 billion years ago, the Big Bang originated from no prior cause, and is the only event to have ever occurred (everything in time and space that can be distinguished from it is distinguished as a result of an artificial distinction, a slice that our minds make). One event without prior cause, and you are part of it; or
• you are a child of God, you were created in God’s own image, as was everyone else, and so each of us is a local manifestation of God, the same underlying self engaged locally and momentarily at being individual; or
• you will be reincarnated into a future that your current acts helped create; the holy are not raised to heaven and the wicked sent to hell, so much as all of us will stay here and keep doing it and doing it until we get it right, and in the mean time will suffer the consequences of our collective actions; or
• what goes around, comes around; or
• I am that I am; I am That Which Is and there is no other.
The truth of these things doesn’t erase the useful truth of being an individual (be rather hard to function if you lost your grasp on that!) but rather parallels it.
None of it means you were Henry VIII in some previous life in some sense in which I was not, IMHO, (and indeed, reincarnation-beliefs are as subject to babytalk oversimplifications as much as anything pertaining to God), but there you have it.
