When coming across people who deny the existence of Reality, they are telling us two things:
- They haven’t experienced the revelation of Reality, (MER).
- So they’re actually admitting they don’t know from personal experience what they’re talking about.
There are many people among us who talk without having any direct personal experience of whatever they’re talking about.
So what do we do?
Nothing. You won’t convince feral hubris, ego. You could make it worse.
Leave them to Reality.
