A question was raised (somewhere in the murky depths of zen dialogue): if there is no time, what about causality.
Here's Dainin Katagiri on this point: "There is nothing in particular that creates impermanence. In this respect, both cause and effect are exactly impermanence in themselves."
In my own narrative: reality is self-cased, i.e. a-causal, i.e. free. Since there is nothing but reality, there is no one (external-to-it or transitive-to-it) to compel it to be a certain way.
In the context of Katagiri's quote, the impermanence could be paraphrased as change, in which case his quote reads: "There is nothing in particular that creates (causes) change..." And his statement that "both cause and effect are exactly impermanence in themselves," in my interpretation, simply means that cause and effect are not-two. He is professing an attempt at a non-dual view of What Is as being seamlessly self-caused, as spontaneously manifesting.
Just another modern-day ape mulling over the ineffable nature of what is (or to be exact, of what was, since we are always phase-behind in our info-processing attempts).
Ra ra ra, kera, kerari-kero!
