Openness is required for balance and openness allows for the needed agility in an ever changing creation/universe. Openness allows for principles of balance to be found and used without needing to maintain patterns that feel controlling, denying or arbitrary.

The essence of what Buddha points to is often valuable and if I was somehow forced into a major religion I would probably pick Zen Buddhism - however, the value of zen buddhism to me is partially in the absence of interference from hierarchy and generally speaking it is such hierarchy that is a hallmark of religion as opposed to spirituality. 

When we know that we ourselves ARE spirit - then spirituality is simply 'being who you are'!
