Perhaps there is a problem of semantics in the phrase "true belief".
There are correct beliefs; for example: I believe that if I stand in the path of a speeding truck, that this body will sustain great injury and perhaps death. In the phenominal universe two things can not generally occupy the same space at the same time without problems.
When it comes to truth/reality, is a belief or thought about a tree, a true tree? Are beliefs about a friend, really your friend, or are they just mental interpritations and drama created in your mind?
When it comes to the actuality of Truth and Reality, there are no true beliefs. Truth is too immediate and vibrantly alive to be captured or circumscribed by a belief or a system of beliefs.
Ponder on what I am saying, and investigate into the dynamics of being, that you may clearly differentiate between a metalized interpretation, and REALity.
This is why there can be great harm in religion. We come to believe that our beliefs are true and real....which they are not. So, we live a lie, and suffer. The mind creates a story and characters which it then fools itself into believing is true, and then worships it's little drama. To worship a deity, is to worship your own imagination. Mental masturbation at it's acme.
