As one contemplates, penetrating deeper and deeper into the nature of reality, one leaves the sensible world behind, transcends the subject/object mode of perception, and experiences one's soul.
We have not been raised to cultivate a sense of Mystery. We may even see the unknown as an insult to our competence, a personal failing. Seen this way, the unknown becomes a challenge to action. But Mystery does not require action; Mystery requires our attention. Mystery requires that we listen and become open. When we meet with the unknown in this way, we can be touched by a wisdom that can transform our lives.
