The term "spirituality" can be used in several ways. The first definition, highly unremarkable and rather banal, is a person's focus on their so-called "inner" world, or the essence of their being. People who are exploring their spirituality frequently talk about feeling "one with the Universe" on an emotional or intellectual level, or "understanding the meaning in life or their place in it", and they do not have to be religious or believe in a god to say so. People who see themselves as spiritual in this way may pray, meditate, or do other activities for these personal "journeys". There is rarely anything magical or even marketable about it.
The second meaning falls right in the heart of Woodom. These are people who see their spirituality as something larger than human understanding, it appears to be magical, and transcendent of all rational ideas. They use the term "spirituality" because they do not have a particular religion, believing in a 'creative energy' that gives an anthropomorphic consciousness to all things.
A third group uses "spirituality" as a code word of sorts for a person who has moved away from organized religion but has not given up God, even though their view of God is really no different than it was when they believed in their religion.
