I also (still) believe that all prophets must've had delusional tendencies and we sometimes have a stronger, closer connection to God. Then we lose our way: we cannot channel it. We get scared.

As I see it, it's just a matter of finding the right balance. Not as in being stable, but balancing the mania, on the edge of the vulcano, or Mount Horeb if you prefer.

Striking that balance you both still hold on to that connection, but you are, by pure conviction and tact (maybe add exceptional circumstances) able to make the delusion into a folie à plusieurs and the believers will convince others and so on. It doesn't have to become a religion, but let it be step forward for humankind.

If anyone knows my employer or psychiatrist: don't!
