Like a looking glass (mirror), correlations are a tool for seeing yourself — your own mind. (See Tools of Taoist Thought: Correlations.) As such, they should appeal to anyone determined to find underlying causes. Of course, you’ll eventually reach The gateway of the manifold secrets as chapter 1 says. Therefore, the correlation’s process may only attract those for whom ‘the looking for’ is more satisfying than ‘the finding’. It is like looking through, rather than at, a mirror’s reflection; the closer you look, the fuzzier the view.
In a way, correlations are a success in failure; correlations succeed in that they fail to provide more than a tentative answer to any question. The good news: All questions are answerable. The bad news: The complete answer cannot be truly fathomed. It is certainly not everyone’s cup of tea. You have to try them on to see how they fit.
Good and bad news here corresponds to how biology drives us to seek answers (good) and avoid the unfathomable (bad). On the other hand, perhaps it is just vice versa. As chapter 2 says, The whole world recognizes the good as the good, yet this is only the bad.
