For me, spiritualism and religion are different.
Where Spiritualism is a view where I feel that there's something bigger than myself, a creative force at work, life in forms and ways that I may not understand but can still respect. Also to some part the 'collective conscience' that can be tapped into through various means.
This makes me look at the world as something alive and worthwile, gives me a reason to think in a more nature-friendly way and motivates me to keep a positive attitude towards the people around me - even 'obvious wrong-doers'.
Religion is the stage where the rules come in. Basic rule sets on how one should live, set statutes on what is right and what is wrong. The more organized side of things, that brings with it explanations and guidelines and teachers and leaders.
And thisone, I have a little more trouble with, even though most religions (if not all) do teach respect, understanding, forgiveness and humility. Because that's not all there is to it and there are always some people who will twist and turn the basis for whatever religion they have to suit their own needs and wants.
The "I am right and everyone else is wrong" thesis just completely puts me off...
Which is why (I think) Buddhism and Wicca are the two 'organised faiths' I've ended up holding on to. They're encouraging solitary practice, paying attention and respect.
But enough on that - to each their own and all that jazz. I'm not here to convince anyone to think like me.
All this is, is how I see it. Everyone should be free to make their own minds up and follow their hearts and minds to wherever they lead - provided noone else gets hurt in the process.
Which is a decent summary of my personal "religious rule-set".
