According to Osho, yes: doctrines, -isms, and even pluralistic catalogues of beliefs are utterly false because truth has nothing to do with mental systems. They are intellectual games. Real knowing arises when the mind falls completely silent; it is immediate, indisputable, beyond argument and counterargument. Truth is lived and seen, not debated, compared, or conceptualized.
Truth isn’t in labels or arguments; it’s what you directly know when your mind is quiet.
