since my understanding was/is that HP is supposed to be exactly NOT internal, but something bigger/not you/outside of yourself.
Within the AA model, one's HP need not be supernatural, but it does need to be outside of oneself. People do it every which way there is...but I'm talking about the HP concept as it is defined by the program.
Interestingly, it was the founders' beliefs that an alcoholic DID indeed need to find God...The God of Christianity, but fearing resistance, the concept of "God of your understanding" was used instead to make it more palatable to non-believers or the unsure. The original program began as a Christian fellowship. Here nor there really, just an historical sidenote.
