My thought is LII.

Post-Enlightenment Buddha represents his perfection as a human so he then is more difficult to type. But I think looking at him pre and post enlightenment gives some clues to typing.

His journey is that he was from a rich noble family and lived a sheltered life with pleasure palaces, which he was content with until he saw the realities of sickness, old age and death. So he was placated with a superficial Si+Fe and then confronted with the limits of that, and wanted to find the true end of suffering I.e. seeking a more substantial Si+Fe. His answer first came in the form of an ascetic holy man who seemed to have found peace by denying the need for physical comfort. Gotama found this temporarily satisfying but again it didn’t go far enough so he denied his need for Si comfort seeking until he became the most renowned ascetic subsisting on only a grain of rice a day.

However, this did nothing for him except make him ill. All the time he was doing this he was trying to understand reality, trying out different schools of thought and dropping them as they proved futile (Ne+Ti). Eventually, he remembers the one time he felt truly complete was not when he was denying his need for Si, nor when he was indulging in it to excess, but when he was seated beneath a tree just in perfect harmony with everything around him (again, si+fe seeking). Note that he doesn’t have this sense of harmony naturally, but is always looking for it, ruling out SEI imo. I interpret this as him seeking SiFe using NeTi methods.

He seeks to recreate this by meditating under a tree and refusing to move until he has found the answer. I like the interpretation above as Mara being his Se PoLR assaulting him with self-doubt, violence, desires etc. After relentless attacks from Mara, what allows Gotama to defeat him is by touching the ground and defending his right to be there, overcoming his PoLR and becoming an immovable object.

What follows is the Buddha being able to “see things as they really are”, which, based on his teachings, is founded in logical categorisation (lots of “if this, then that” sort of statements, as well as lists, categories and logical steps). Even his ethics isn’t based on relating to people on a purely emotional level, but from the wisdom of understanding reality. The ethical precepts aren’t there because they are nice things to do, but because they align your actions with a dharmic understanding of reality.

Finally he becomes Enlightened and self-dualises, finding the peace and understanding he has always been seeking. The last test is his decision to teach, because he initially doesn’t want to spread what he has learned but is asked to by a God. He surveys the world and sees the potential of all living beings to accept his message, and decides to go forward and teach, often adapting his teaching to the person he is speaking to so that they always get the right message for their level of readiness and understanding (fully gaining control over Fe).
