If a lens reveals a truth about reality isn't it true? Also I don't know what artificial distinction you're making between this and a religious belief. That's what all religions do.
I never said that about what the lens reveals. The thing is that it doesn't reveal truth. It's a tool that you only use when you need, not a dogma that is guaranteed to hold.
"There is a self I can pinpoint" is as valid as "There isn't a self I can pinpoint". "God(s) exist(s)" is as valid as "God(s) doesn't(don't) exist". When I have this problem, I can use a hammer. When I have this other, I need a CNC mill. That's my understanding.
Some religions are teleological (they have purpose mapped out) and you just have to have faith or commit some actions. Others give you some necessary but insufficient tools, because the truths they want to express to you are somewhat ineffable.
