I just reread this after reading a collection of Rumi poems for the first time. While reading Rumi, I was reminded of these tablets over and over, and then had to go back to read them again. The symbols and iconic Persian stories that this book has in common with Rumi had a new dimension to them this time around. I feel like I got more out of it than I have before.
Anyway, it's a wonderful little book, very much in the tradition of Sufi mystics, pulling on that tradition. But of course there's a lot to learn here.
