Spiritual Truth

Dawkins' chapter 8 - Beliefnet

When you let the material/worldly override truth, it is spiritual suicide. Spirituality is as necessary for human survival as eating and pooping. Spirituality is the function of the mind that is the reward center for discovering exceptional beauty, truth, relationships, and emotional truth. In a spiritual experience all mental activity is subsumed to the importance of the moment, and the truth contained therein.

Spirituality is not necessarily the province of religion, but religion can be a cliff notes version of spirituality for those who cannot or will not do the study and introspection necessary for personal spiritual truth. Religion does not prevent and in fact encourages the study and introspection but many ignore it and let theology override spiritual truth.
