We become aware of the sacred because it manifests itself, shows itself, as something wholly different from the profane . . . something sacred shows itself to us . . . something of a wholly different order, a reality that does not belong to our world, in objects that are an integral part of our natural "profane" world.
Mindfulness is an ancient form of meditation in which one pays attention to the present moment and all that's unfolding in that moment, both within and around one. It's known also as conscious living because the person practicing it is forming an aware and intimate relationship with each moment.
When practicing mindful meditation we aren't striving to do anything, we aren't grasping, struggling, thinking, expecting, or wanting but simply letting whatever is there be there and paying attention to it in a non-judgmental way. We come to terms with reality as it is, bringing all our awareness to it, breathing with it, attending it.
