Even as a full in Jdub, I could never understand how going to all the meetings, put lots of hours in the FS, answering up, preparing for meetings etc etc... somehow equated with being spiritual. It really is totally meaningless. Although I did all those things, it left me completely cold.
To me spirituality is sitting in a beautiful place outdoors and feeling at one with the surrounding nature (whether a believer in God or not), soaking up it's beauty, listening to birds sing and feeling your emotions soar. Having a great meal and being surrounded by all your family and just having fun and enjoying each other's company and feeling the love. Listening to an amazing piece of music and letting it capture your soul. Every human on this planet has a measure of spirituality. It just cannot be defined by religious rules!
