The purpose of meditation practice is not enlightenment; it is to pay attention even at unextraordinary times, to be of the present, nothing-but-in-the-present, to bear this mindfulness of now into each event of ordinary life.
It is significant that the Latin word "templum" originally meant a vast space, open on all sides, from which one could survey the whole surrounding landscape as far as the horizon. This is what is meant to CONTEMPLATE: to "set one's sights on" Heaven from the temple that defines the field of vision... The temple is the place, the organ of vision.
