The rational, the observable and measurable capture some truth. We are blessed to live in a world of science and mathematics used to sustain us. To focus only on this one truth, or aspect of the whole, is to perceive the bark as the whole of the apple tree. It is to enjoy the apple without its core of seeds.
Uncloaking the intricacies and mechanisms of Creation does not explain the abundant love which is within, between, and that envelopes us. For that truth we must tap into the spiritual. We must simultaneously go within and beyond ourselves. We must be long enough to perceive. When we do that, we experience another truth: that the One binds you and I together with the polar bear and the ant, the blade of grass and the artichoke.
