> The concept that knowledge should be witheld from people until they're ready is so anthical to our current beliefs.

It is not knowledge that is witheld. It is text. I also propose to you to consider the thought that true knowledge is only obtained by experience. The fundamental issue with psychologically potent text and images is that it can induce convictions based on misreading and misunderstanding.

IFF you can exercise the necessary self control to avoid premature utility of the I Ching, the entire work is of course a profound metaphysical model of human reality through the lens of Taoist sages based on a simple and elegant axiomatic framework that uses the concept of state-transitions & numbers 2 (forces) and 3 (places) to develop a comprehensive metaphysical system to consider "all things under the heaven".

Mao tried getting rid of it. (I don't agree with all this btw, but just fyi.) https://en.wikipedia.org/wiki/Four_Olds
