Thank you, Alexander, for informing me of a new-to-me mystic. Henry Suso sound interesting. I split your comment about him and started a new topic here dedicated to Henry Suso so that we can examine the record of him, and see what it is about him that makes him a mystic.
While working on 4 university degrees I took several classes on mysticism, so I have read a fair amount of Evelyn Underhill's work, and read other authors who are publsihed on the topic of mysticism. What I came away from that study is most authors who write on the topic of mysticism have a poor understanding of it, and most likely it is because they are not mystics.
So, what I saw in most of that study is these authors mostly wrote on people in history who had a reputation of being mystics, but what I saw was only 10% of those so-called mystics were probably the real deal. The rest seemed to be members of a wealthy familiy who often lead a religious life, but never demonstrated authenti mysticism, and this is true for Evelyn Underhill.
My goal here is to inform people regarding mysticism, and to build a dialog about mysticism, and discuss the history of mysticism. So, I am always happy for others to bring to our attention a mystic that some of us may nnot be familiar with. So, what is it about Henry Suso that makes you believe he was a mystic?
