I believe being a transpersonal artist involves the synthesis of so many things- representing all manner of ideas, philosophies, sciences into a visual representation built with sacred and personal intention.  

I saw this really great definition of Transpersonal Psychology (Wikipedia) which is perfectly aligned to the visual artist who practices with this orientation: "A school of psychology that studies the transpersonal, self-transcendent, or spiritual aspects of the human expereince; transpersonal experiences may be defined as experiences in which the sense of identity or self extends beyond (trans) the individual or personal to encompass wider aspects of humankind, life, psyche or cosmos."
