If mysticism is just another law we haven't discovered, then no need for the mysticism. Let it be what it is, ponderance of a system we have yet to fully understand.
Imagining and describing systems we have not fully conceptualized or lack enough understanding to systematize is fantastic, but complicating it with mysticism, magicks, divine intervention, and etc. that we hold very little relational evidence for only clouds our ability to chase the answers.
