"The highest form of spirituality is that which leads a person to look deeply into and question everything...every form of conventionality and lazy thinking...not just the conventionality and lazy thinking found in organized religion. Spirituality asks the great questions and the small ones. It questions every "rule" and re-examines it. It questions every role and re-examines it. It looks beyond the surface. It questions self as well as questioning others. It unites all the disciplines...science, philosophy, art, commerc. It does not divide and separate...(you don't look suddenly shaplier? Heh!)...it unifies the apparent opposites." - Little Hawk

From where do you get this broad definition of 'spirituality'? Spirit and spiritual are examples of words with multiple definitions, including ones which conclude that they describe imaginary concepts. The above makes it sound like the Universal Solvent.
