Spirituality is personal to each individual. There are many books, online articles, blogs, even videos on the subject. I have written articles on what I believe spirituality is, but again, these are my views, which may or may not be what you believe. Many others have written their views down in books, blogs, and articles. Some things I agree with, some things I do not.
Spirituality can be drawn from holy books as well such as the Bible and the Koran, but it may mean nothing to you as a Buddhist. The point is, there are resources abundant, but each person has to decide for themselves what makes sense to them and what it is they believe.
On the Spirituality site there is a section on reviews where several books have already been reviewed by a previous editor. Perhaps that would be a good place to start if you are looking for some reading material. If a book seems interesting to you then perhaps it would be a worthwhile read.
