What is the connection between "mysticism" and ...

Mysticism is is the pursuit of achieving communion identity with, or conscious awareness of, ultimate reality, the divine, spiritual truth, or  God through direct experience, intuition, or insight. Spirituality is  concerns itself with matters of the spirit. The spiritual, involving (as it may) perceived non-physical eternal verities (or even abilities) involving humankind's ultimate nature, often contrasts with the earthly, with the material, or with the worldly. A perceived sense of connection forms a central defining characteristic of spirituality — connection to a metaphysical reality greater than oneself, which may include an emotional experience of religious awe and reverence. Equally importantly, spirituality relates to matters of sanity and of psychological health. Like some forms of religion, spirituality often focuses on personal experience (mysticism) and prayer.

Profound question, Shai. Worthy of a long answer, but this box is small and the moment is limited.

Spirituality is the awareness that there is a spark of the Creator within oneself and every other element of creation. This spark is imbued with purpose.

Mysticism is the discipline of increasing that awareness and the ability to make connections between the spark of the Creator in oneself and that spark in another, and be moved to further the purpose of creation.

Ah, I see this box is expandable. Unfortunately, the moment is not. So, that's a quick response. 

How would you answer your own question? And what other questions does my response generate?
