There are great treasures in the soul: there's faith and love, there's awe and wisdom. All these things you can dig — but if you don't know where to dig, you dig up mud. If you want to get to the gold — awe before God, and the silver — the love, and the diamonds — the faith, then you have to find the geologist of the soul who tells you where to dig. But the digging you have to do yourself.
Then there is the listening at the gates of the heart which has been closed for so long, and waiting for that mysterious inner voice to speak. When we hear it, we know it is the Truth to which we must now surrender our lives.
