Why do you want to be spiritual?
To get mental peace and happy what more.
Spirituality on the other hand is, to me, a certain acknowledgement of something greater than what we can perceive, a force in the universe that may not necessarily be scientifically measurable, or simply not yet. I’m disinclined to call this concept “God” because of the many associations that word has with people, including myself. I don’t believe at all in there being some deity-like being that “has a plan” for us or that has preferences over things that matter to us here on Earth. The idea that “God hates fags”—to use the most extreme example—is not just idiotic, it’s downright offensive to our accomplishments as a species.
To put that in context, spirituality doesn’t stem out of any xenophobic ideas nor out of some desire to explain the unknown, but rather out of the acknowledgement (and welcome embracing) of knowing that we are incredibly insignificant little specks of carbon in a vastly huge universe, full of things we don’t know (yet). It is, in a way, a sense of childlike wonder about the universe being able to show us so many things we can’t even imagine, but a firm belief (or leap of faith) that such things do exist out there.
The ideas behind many religions are positive, supportive and tolerant, but the requirements of adherence to some things (rules, traditions, rituals etc.) gives them a certain self-defeating trait that doesn’t work for me. An intrinsically open, tolerant and free religion is paradoxical because it would have no members associating themselves as such, yet countless of people subscribing to it. This, I would say, is a pretty accurate description of a lot of atheists and agnostics.
