You think I don´t understand, I think the opposite. It´s normal. But I'm glad you see the value of the original texts, not the commentaries (at least most of them) that came afterwards.
But if you believe the tao as a path to walk, the I will show and bring meaning to different paths you can tread, instead of just the ones you are used to or can think of. If you choose, you can walk, or avoid, the path that is shown. And the wise of the I Ching is to understand what's likely to happen in each dynamic chosen or change achieved. It enlightens a lot your walk of life. But if you understand divination in a context that your path is predefined as fate, like many other traditions (that came later and influenced us) do, then your understanding of the tao is as narrow as you make it in you mind: a fate to be fulfilled, a path you can't escape from, a Tao already created by something never conceived by taoism itself.
We have to strip ourselves from religion's omnipotence and omnicontrol, which is very deeply embedded in our culture, to understand what is to foretell what is bound to happen unless you change your path, and future changes with it. As it happens in the physical world. Understanding what Nietzsche meant by God is dead helps a lot. Existentialism, existence preceding essence, is much closer to taoism than any religion or esoteric belief. Yin and Yang continually create all there is. Understanding them helps you foresee where things might lead to, if you experience yin and yang forces within you the same way showed by the oracle. Unless things change. And it does, all the time. Sorry, no comfort there. I understand if you don'l like my views.
