Hi Phizzy. I grow in my spirituality by learning and being honest with myself. I am not afraid to read or consider other points of view. I think that a growing spirituality involves more than "getting closer to god". I think it has everything to do with improving as a person and finding your purpose in life. With developing a philosphy that is both solid, yet allows for learning and growth.
I think that if "spirituality" causes you to look down on people, to rule people out, to give up on people, so that you can be right or better, than you go backwards and not forwards.
Being a spiritual person is not about finding a group of people who agrees with you so that you can think your group is right and others are wrong. It's about being a light in the world to everyone, to be yourself while allowing others to be themselves.
