Mysticism

Mysticism expresses an unseen (possibly) ultimate reality in unusual ways, through other than cognitive or sensory means. Mystical experiences can be revelatory with a transcendent quality of another worldly essence. There is an unknown factor or element of surprise involved in the included works, sometimes simply expressed symbolically as it is challenging to recreate something unearthly in material terms.
Mysticism converges with the unknown! How do we convey that in our world of the senses becomes the challenge.
