I do not think reading the mystics would hurt you myself: you say you must avoid books which deal with 'feelings' - but the mystics don't deal with feelings but with love which is a very different thing. You have too many 'feelings,' but not nearly enough love.

Evelyn UnderhillNever let yourself think that because God has given you many things to do for Himpressing routine jobs, a life full up with duties and demands of a very practical sort---that all these need separate you from communion with Him. God is always coming to you in the Sacrament of the Present Moment. Meet and receive Him there with gratitude in that sacrament; however unexpected its outward form may be receive Him in every sight and sound, joy, pain, opportunity and sacrifice.
