Spiritual is defined as a concern with matters of the spirit involving in humankind's ultimate nature, often contrasts with the earthly or material or worldly. A connection to the metaphysical reality greater than oneself, which include the sence of a God or gods, or include an emotional experience of religious awe and reverence.
I personaly consider spirituality as a state of knowing the meaning of life, a connection with oneself and a higher being or creator. The principal teacher of values, ethics, and beliefs in it's pure uncontaminated form. Also as a transcendental demention of life beyond self where awareness and appreciation for a higher being exists.
But then again, what do I know.
