Such a realization is a mere step beyond the belief-system. It is a healthy state of ignorance which reveals that there is a light at the other end of the tunnel. Belief is religion, belief is dharma in the sense of established religion - full of doctrines, theories, and so on. Dharma holds the community together, prevents the individual from disintegrating. However, it is not oneself.
Insight enables belief to fulfil itself in Self-realization.
It does not militate against even organized religious institutions but puts the spirit back into them. Light does not drive away or destroy darkness - it reveals what it is. But right belief is a ladder that helps you get there, thank God and thanks to the belief itself.
