Maybe stopping is better than starting, listening better than acting, and stalling better than moving. Maybe one cannot happen without the other. Maybe stopping is necessary to starting, maybe acting cannot happen without listening first. I believe that our understanding of spirituality has been distorted and ruined by our artificial judgments and our one-dimensional understanding of our relationship with God. Let me point out a couple of interesting characteristics of this graph.
Every high is followed by a low and every high is preceded by a low.
Maybe what the graph means is that you cannot achieve a high without first achieving a low. Maybe lows are not low at all, but just part of the highs. When you look at it like this, then getting stuck is not only a necessary part of spirituality, it is a prerequisite to spiritual growth. Most of the Church considers being stuck a negative, a sin of failure or burn-out, an indication that a person isn't working hard enough on their spiritual life. If you feel stuck in your spiritual life, then you aren't doing something right because no one should be stuck with God.
