As with mind, these pure ideas are only contingent, re: theory-specific, logical starting points, a way to deny to speculation its inevitable descent into self-contradiction. — Mww

Yes, I agree. Likely, we can't help but to speculate; the starting point of all constructions. And yet, like you suggest: end of the day, they never stop being constructions.

Well said.

It is impossible to generalize since we are all unique. Some need a guru, a sangha, an advisor, a wise friend. But these are all things that must be left behind. There is really nothing to be learned, nothing to be gained, nothing to be known, beyond simply becoming able to relax completely and let go, and be yourself without any fear of missing any mark or any truth, or making any mistake.

The deepest illusion, the most profound nonsense that needs to be expunged is the idea that enlightenment consists in finding the Absolute Truth, coming to know the Ultimate Essence of Reality.

Yep. And obstructions. Just being is not a condition of knowing anything.

Quite, I remember when I met and became friends with a guru at his ashram. I had expressed an interest in meeting him and when he came to sit with me, he was defensive at first which surprised me. Then I realised that most people who approached him in this way wanted him to lift a burden, to somehow solve their problems. Or be someone they can lean on (metaphorically) and somehow leave all their worries behind. When I conveyed to him that I didn’t want anything from him and just wanted to hang out in friendship. He was visibly relieved and we spent a week enjoying the practice of puja, with a sense of fun and humour. During which I realised that there was a complex dynamic of seekers, worshippers, people working through their own spiritual, or mystical processes. All using him as their focus, crutch, motivation. It was very fertile ground and I made some important realisations there.

Yes, to remove the impediments to being yourself, in stillness and joy, or contentment. And yet there is still value, meaning and education to be gained alongside that and work that can be done.

Yes, but this along with other aims of the seeker are understandable, because one is blind at that stage. Blind in the sense that there is no sense of direction, no goal, no means of attaining one’s perceived goal. One is just trying anything that looks like it might work. This is where a guide is useful, or a school.
I liken this stage to questing, a series of quests that one undertakes and comes to realisations about oneself and the path and the direction of travel. Eventually one reaches a point of stillness, focus and direction*.

What this indicates to me is that this is not a process of intellectual learning, or wisdom as such, but more one of a development in the self. A process in the body, the being.

*Many seekers never reach this point.
