To me, spirituality denotes the condition of an individual who is concerned with and on a search for how ulitmate questions affect both themsevles and the rest of the universe. I think that the individual can fit activity in an orgainzed religious body into their search. However, I don't really believe that institutionalized religion in itself has much to do with spirituality. In other words, some individuals find useful the tenets of a particular religious body but the concern of many institutional religions for making and enforcing rules do not, I think, contribute that much to facilitating the individual's search. I am thinking mostly of Christian denominations here, as those are the religious institutions I am most familiar with. And, I am certainly not saying that all institutional religious organizations are the same in the respect of enforcing a particular set of rules and orthodoxy of thought on their adherents.
Does that make any sense?
Let me try to say it differently. I believe the spiritual person is one who thinks seriously about ultimate questions: Do a god or gods exist, and what does that mean for the individual, for the world, for the universe? Is there life beyond - after or before - what we recognize as physical existence in the visible world? Is there meaning to our lives, to the world and universe we live in? What is that meaning? What are the best ways to conduct ourselves in relation to others, in relation to any possible god or gods, in relation to the world and universe? There are other such questions, but these are the ones that come most readily to mind right now.
I think an individual asking these questions can use adherence to and activity in organized religion to find possible answers to the questions. A particular individual might find value in the particular beliefs and dogmas of a particular religious group. However, I also think that sometimes institutionalized religion - especially some Christian denominations, as those are the religious institutions I am most familiar with - can get in the way of the individual's search due to their emphasis, even over-emphasis, on obedience to rules. You have to dress a certain way, some denominations hold. You have to wear your hair in certain ways. You can't eat and drink certain substances. You must give a certain set percentage of your income to the church. And on and on. I think all that gets in the way of thinking about the more universal, less material questions that are, for me, what make up spirituality.
Now, I'm not saying that certain material practices and disciplines cannot contribute to an individual's search for the ultimate. They can, of course. What I think is not productive is the institutional insistence in some churches on a one-size-fits-all enforcement of rules and rituals, with the judgement that all those who do not or cannot adhere to these rules and/or participate in these rituals are unacceptable in the sight of who or whatever the institution holds as holy or sacred. I think the spiritual search is much more individual than that, because we are not all the same - physically, emotionally, mentally. Because we are all different, I just do not believe that there can be only one path to the ultimate.
Well, I still don't know if that makes any sense at all.
And I'm sorry if I've offended anyone who believes differently than I do. But I have only my own experiences to go on, and this is what my experiences have shown me.
Edited, in the next to last paragraph, to try to clarify what I was trying to say. I'm not sure I was able to, but I've tried. What I was trying to say there is that rules and rituals can be helpful to the spiritual search, but that making those rules and rituals binding in the same way on all individuals is not productive because not all individuals are the same.
