A big problem that all of us have to face is deciding what is really important in our lives and what is trivial, to learn to differentiate between what is passing away and what is enduring. The English medieval writer John of Salisbury wrote: It’s not possible for one who, with her whole heart, seeks after truth, to cultivate what is merely empty. That is the challenge that each of us has to face: not to cultivate what is empty because with our whole heart we seek after truth, after love. Meditation is so important for each one of us because we live in a society that is in real danger of losing its sanity. A human spirit that is healthy demands expansion. All of us need room to breathe, to expand, to fill our lives with truth, with love. And if we are healthy, we know that we must cross all the frontiers to what is beyond.
