I believe the answer is:

mystic

(Other definitions for mystic that I've seen before include "Otherworldly" , "One attaining high levels of spirituality" , "Believer in truths beyond tangible proof" , "One who seeks spiritual union with God" , "Relating to occult rites" .)

I've seen this clue in The Sunday Times and The Times.
