Several people in my family have a hard time with their "Things" they don't want to get rid of anything in case they might need it. The collection of things give them an identity of sorts. I have very few things and at least 4 times a year I go through all of my stuff and rid myself of it.
I'm not saying I am right and they are wrong nor am I saying that "thing" collecting could ever work for me. I am aware that in the world of the spirit, you must constantly make room by shedding things to make room for the new to come in. "In with the old, out with the new", it's like my favorite analogy from an eastern religion that compares life to a bowl. When the bowl is empty, then and only then is it useful. One the bowl is full, it isn't any good to anyone. Life is about filling, emptying and refilling and emptying our "Bowls".
By holding on to useless old ideas, we don't make room for any new one. New ideas and new experiences are our lifeblood. Since there is no graduation of life we have to constantly keep trying to grow and experience or we get full, stagnant and infectious.
The spirituality I understand at the moment is about the flow of the universe. When I am going against the "flow" it hurts and I get know where. If I try to remove myself from the "flow" all together I am so desperately lonely I want to die.
But, when I am on my game, letting go of old ideas, old pain/hurts and a mind set on personal destruction, I can inter "The flow".
When you are flowing you know it. Things happen without struggle and a tree is a tree, a flower is a flower. I'm being what I was put here to be.
The only true peace I have ever known is in "The Flow".
