Question: You seem reluctant to recommend books or courses on mysticism.
But each personal experience is different. it is tailor made for each individual’s stage of development.
Answer: Yes. In my own experience, each human experience of anything is the only beginning of all knowledge.
Consequently, as a mystic, my reading and listening, my learning style, delivers my needs at the time, when I’m ready. My way and my time are never going to be your way or time.
No one else’s way and time are ever going to be exactly appropriate to you or other people all the time, either.
A spiritual teacher was asked why he sometimes gave different answers to different pupils.
The teacher explained what all mystics have experienced: “Each individual’s ability to fully apprehend Reality is unique, and different to different personal circumstances and attributes.”
So my ways are not your ways, and yours are not mine. Similarly, Reality’s ways are not our ways and our ways are not Reality’s …
If your calling to Reality is true you’ll always find what your real present needs are. Clue 1: they’re not worldy!. Clue 2: they don’t always give the answers you’d expect. Clue 3: they definitely change as you change. Clue 4: they’re fundamental, simple. Clue 5: they free you to be the real you, without baggage!
In my experience, if you are really called, not caught in books, courses or ideologies, you will be gifted with two more abilities to help you on your Way: the ability to listen to the exclusion of everything else, and discernment.
(Beware – Reality can also be insistent to ward you off what you don’t need! Ignore such warnings at your peril. Wanting is no part of spiritual development).
Mystical Experiences of Reality 
I very much like the idea that books and courses are “useless” for these purposes. Whatever I am and in whatever stage of development your post rings very true for me. I started to read “Ingram, D. M. (2018). Mastering the Core Teachings of the Buddha: An Unusually Hardcore Dharma Book” the other day and became frustrated and irritated. He seems to convert a few simple ideas into massively overcomplex dogma and for the life of me I don’t understand why.
It is probably as simple as you say: his ways and time are not mine.
I am more sure than I have ever been that we (humanity) are lost, misguided and foolish. I don’t think there is much wrong with the physical world itself (other than the fact all animals survive by preying on each other) and indeed I receive much from physical beauty, calm, and those aspects of nature which do not revolve around greed and survival.
Whether this brings joy, peace and contentment is another matter. It often does but only when I abandon the worldly. To take any notice of politics or business or the social media in general is an anathema to me.
As to “wanting”, how right you are. Ignore reality’s warnings at your peril – yes, a lesson I should take to heart.
All best wishes
