Prayer may take the shape of sacrifice, supplication, adoration or meditation; it may even appear in simple daily acts of kindness; but it is always the outer visible sign of an inward communion with the Divine.
It is strange how much we resist the inherent peace and quiet that is always possible. Perhaps this is because resting in simple presence is so foreign to a lifelong habit of mental complication, and we may have confused complication with a sense of aliveness. We may assume that having no particular mental project would result in boredom. Or we may be overwhelmed by how vast and free life suddenly feels when our minds are not on the hunt.
