Hi there,
I am more and more convinced there is no end to intellectual Dhamma confusion, in this sense, that we can talk endlessly about Dhamma concepts. We cannot really solve this intellectual confusion by reading more texts, study even more intens, listening to many teachers. That is my personal experience, at least.
Maybe some people have come to some intellectual clarity, and have a big picture in which any piece of the Dhamma puzzle fits. With much effort one has a kind of consistent Dhamma story to tell oneself and others. And one feels that this consistency is the proof that it must be true Dhamma. I think i see this a lot.
That can look impressive. But, my experience is, if you investigate all that, you will see that this socalled consistent Dhamma story is also formed, constructed, and also based on highly subjective choices, emotions, rooted in tanha. It is not really all that neutral, objective, as one tries to tell oneself and others.
If one after many years of intellectual confusion about Dhamma stuff has finally a consistent big Dhamma picture to tell oneself and others, ofcourse one will feel more peace, more ease, cooling down, but i feel it is not real. It is forced. It is based on ideas, on more attachment, but not on really letting go, detachment.
Moreover, the personal fire, tanha one still has, is now totally aimed at sharing and prooving that consistent Dhamma story to be true. It is always about prooving ones own ideas, choices, explanation.
I believe it shows how the tendency to become radical, polarize, become fanatic is very strong. I think it is a real danger personally, for mankind, for the Sangha, for all beings.
