It is my understanding that duality is intrinsic to being human.
Yeap, you´re right, that is the reason we are born in the first place (when we are born, we are meant to die); this is the meaning of Karma. Zen phylosophy says: "Do not choose", because everything else is duality. Your likes and dislikes are the tricks of the mind to stay in this cyclic existence; mind cannot exist beyond cyclic existence.
As long as we live in duality, we will continue reincarnating unconsciously. If we die unsconscious, we are born unsconscious; that is why we can´t remember past lives so easily.
Buddha´s first discourse after enlightment is very well known, and is the foundation wisdom of the Buddhist tradition:
The four noble truths:
" 1. Suffering (dukkha) : literally means "unsatisfactory circumstances". Involves birth, aging, illness, death, being with what is displeasing, being separated from what is pleasing, not getting what one wants, and "in brief" the five aggregates-of-clinging (pancupādānakkhandhā).
2. Suffering's origin (dukkhasamudayo) is desire (tanhā) for mundane pleasures; all that is taken away by death is mundane.
3. Suffering's end (dukkhanirodho) comes from the relinquishment of freedom from this craving.
4. The path leading to suffering's end is the Noble Eightfold Path."
Suffering is caused by duality, and suffering´s end happens with trascendence of duality.
Also, if you are right about this, only a very, very small portion of humanity has ever transcended.
Bingo.
When Jesus or Krishna, or any Buddha talk, they are not talking from the self; it is God speaking through them, sort of speak. God is just trascendence.
Every single Buddha of the past have declared: "I am God", because they are just empty vehicles on which God functions; this is how to read the scriptures. Jesus was not literally "God", it was God declaring it through Jesus.
"Yeshua says: I shall choose you, one from a thousand and two from ten thousand— and they shall stand as a single unity" - Gospel of Thomas.
Jesus won´t choose you, it is God, trascendence that will choose you (only a few).
Notice that this cannot be in the cannon, it goes against any "following"; it cannot be adapted to a lucrative business, the church needs its followers.
"How should one chase a thousand, and two put ten thousand to flight, except their Rock had sold them, and the LORD had shut them up?" (Deuteronomy 32:30)
"If there be a messenger with him, an interpreter, one among a thousand, to shew unto man his uprightness" (Job 33:23)
"Which yet my soul seeketh, but I find not: one man among a thousand have I found" (Ecclesiastes 7:28)
