What are the views of Reformed Protestants on Christian mysticism?

Building upon my previous question https://christianity.stackexchange.com/q/101680/61679 and the excellent [answer](https://christianity.stackexchange.com/a/101815/61679) by GratefulDisciple, I would like to delve deeper into how Reformed Protestants understand and respond to the concept of [Christian mysticism](https://en.wikipedia.org/wiki/Christian_mysticism) . This concept has a long Patristic and Medieval tradition present in both the Catholic and Eastern Orthodox Churches, and is also evident in more recent movements such as [Pentecostalism](https://en.wikipedia.org/wiki/Pentecostalism) and the [Charismatic movement](https://en.wikipedia.org/wiki/Charismatic_movement) . To keep the scope narrow, I would like this question to focus solely on **Christian mysticism** as traditionally understood by the Catholic and Eastern Orthodox Churches, leaving the discussion of the more recent Pentecostal and Charismatic movements to a [separate question](https://christianity.stackexchange.com/q/101848/61679) . Do Reformed Protestants share an appreciation for the mystical aspects of Christian spirituality as traditionally understood by the Catholic and Eastern Orthodox Churches?
