Reddit reviews The Essential Writings of Christian Mysticism (Modern Library Classics)

My personal suggestions, study whatever you can on the following:

1. The German/Rhineland Mystics and those they influenced: Meister Eckhart, Johannes Tauler, Henry Suso, John of Ruysbroeck, Nicholas of Cusa, Jakob Boehme, and Angelus Silesius.
   
   
2. Greek and Desert Fathers: Dionysius the Areopagite, Maximus the Confessor, Evagrius Ponticus, St. Isaac the Syrian, anything on Palamism/Hesychasm, anything on theoria/theosis.
   
   
3. Manuals for practice: The Cloud of Unknowing, the Philokalia, Abandonment to Divine Providence by Jean Pierre de Caussade, the Imitation of Christ by Kempis, the Theologica Germanica, the works of Theophan the Recluse.
   
   
4. The famous Carmelites of St. Teresa of Avila and St. John of the Cross.
   
   Two decent collections on Christian mysticism worth checking out are Bernard McGinn's The Essential Writings of Christian Mysticism and James Cutsinger's Not of This World: A Treasury of Christian Mysticism.
   
   Of all the above, the two ultimate mystics in my opinion are Meister Eckhart and Dionysius the Areopagite, and the two best works on practice are the Cloud of Unknowing and the Philokalia. Studying those four areas would be the best in my opinion.

Try reading about Christian mysticism. This book has a pretty great collection of mystic writings, and it was at my local library. Hopefully I didn't totally misunderstand what you were talking about, but it was encouraging to me to read about the history of mysticism within Christianity.

This site gives a fairly good overview: "The starting point of mysticism is encountering the Goodness of God. Not a conditional "goodness," but pure Goodness itself, with a capital G. This is Goodness without opposite or contrast, not the good in "good and evil." Goodness filling the Universe just as God himself does, so overwhelming in Good, that there is nothing possibly non-good there, no matter what appears to be otherwise."

Look at Bernard McGinn. His scholarship on mysticism is very influential.

The anthology he edited, The Essential Writings of Christian Mysticism, is really really good. You'll get a taste of everything.
