In our endeavor to understand life we experiment externally, which is science in order to understand the laws of life internally, which is spirituality. As we see the universal laws unfold and how they apply to our mind, we understand our relationship to the whole. By being good we find out what makes us happy and by being bad we find sadness, therefore to be content and happy we must find the best way to live. To live a good life we must deliver an unconscious pattern into a conscious system, which is what spirituality does for us. It is just as important to understand our internal self, as it is to understand the external self in order to be healthy and happy. We need to learn to watch the inner reactions of the mind, the same way we observe events in the outer world for self-preservation; consequently, our mind becomes aware of itself as a part of God's pure consciousness.   Christian Mysticism
