"The real does not die, the unreal never lived." - Sri Nisargadatta Maharaj. There is a lot of wisdom in what you write; if you remove "Christ" from your writing you are in alignment with many of the world's spiritual traditions. Particularly, Hinduism and Buddhism. But then Christianity's origins (through its old testament writings and early new testament writings that were added during the first couple of hundred years after Jesus died) are intertwined with the east as can be seen by attending any traditional Orthodox Liturgy.
If i recall, Nisargadatta, upon meeting his guru for the first time, was told straight up, without any chit chat, "You are not who you think you are". After three years of practice, he knew, with experience, at all times, just what that meant.
This reminds me of Jesus query amongst his followers, "Who do you say that I am?"
And if you asked him who he was, Jesus might say something like, "I AM".
The priests among the Jews, who didn't like him much, then accused him of blasphemy, for using language that only their god would use. To which Jesus would reply, "Assuredly i say to you, before Abraham was, I AM".
What Christians today don't realize, anymore than the Jewish priests realized back then, is that this phrase, "I AM", had been a standard mantra in a certain sect of Hinduism long before Jewish priests wrote their propaganda piece on scrolls of lambskin, borrowing from legends all around them at the time.
It is such a standard, and important mantra, that Nisargadatta titled a book, he called, "I AM THAT", wherein the first chapter is titled, "The sense of I AM".
This is all to suggest, even more to suggest, that Jesus understanding of his Self derived from the practice of some very ancient, BUT NOT JEWISH, states of mind, most notably emanating from an obscure sect of Hinduism called Advaita Vedanta, or better understood as Non-Dualism.
Who, or what you really are, is central to that state of mind, and would be why Nisargadatta was told, straight up, first thing, he was not who/what he thought he was, at the time he approached the guru. He only changed his name to Nisargadatta when he understood it.
Nothing in Judaism teaches anyone to question their manhood, or their womanhood, or their snakehood. Judaism proposes the advent of a Messiah. But as i've long noted, Jesus did not agree he was their Messiah. As "I AM", Jesus was much more than their mere Messiah, and would be a brand new kind of savior, saving something completely different from what Jews (and today's Christians) were trying to save, namely their nation-state and their personal individual sense of existence, which is not real existence, according to a non-dual state of mind.
While nothing in Judaism teaches anyone to meditate on existence apart from a body,
everything about non-dual, or advaita vedanta versions of spiritual psychology moves
all students toward the realization of existence as the Supreme Being, rendering every other identity nil, null, or nothing.
If all students are the Supreme Being (I call that "Christ", others call that "Brahman"), then as people, we all must be fraudulent versions of the supreme fraud upon our Self. This is basically what Jesus was teaching, especially when speaking of oneness, all coming (descending) from the same place, and all ascending back to the original place.
As a savior, Jesus' brand of psychology saves Christ from the fraudulent substitutes for Christ that suffer in hell due to mischaracterizations about the true Self.
