The difference between Religion and Spirituality can be very different for each person. However, I see religion as a set of rules, beliefs, and guidelines that you have to follow in order to be a part of that religion (or to follow it correctly) like the 10 Commandments. In this way, I see "religion" as made by man to exclude others that are not of the same mindset. I combine beliefs from many different religions into my spirituality.
Spirituality is much different in that it is individualized and part of a community at one time. Spirituality is a state of being that allows you to determine your own beliefs and guidelines, while at the same time connecting to others of a higher spiritual mindset. You may each have different beliefs but work together so you can all move forward on your individual spiritual paths. Spirituality is more than just saying you are. You have to feel it and continue learning about yourself and others in order to grow.
