Inventing personal spiritual concepts.
Tastes differ: some prefer to adopt a Religion, solid and well promising, a few others choose to follow personal spiritual paths, more demanding but it will probably lead to something that really fits your mind.
This is usually given a negative connotation: do-it-yourself religion.
Following a predefined scheme of what you must believe seems to be far better than trying to imagine Life and what’s beyond by yourself, with concepts you can actually understand. Is it really that better?
If each exsisting Religion would be “open-source”, completely understandable, one could modify the grey parts, dogmas, etc… but in the end, would it be worth it?
So what about starting from scratch a new one? Hmm too hard. Let’s “simply” build up some basic principles of how the Cosmos could work, what/who the Infinite/God is, who is You and what is around you.
The trick to go on is thinking about very simple basic principles: if you’re thinking about something, try to think about its root. Root concepts will keep you from getting lost into thousands of useless frills.
This kind of religion obviously will not like to those who pray their gods to obtain benefits or who wants his/her wishes to be fulfilled. In such cases I’d rather prefer atheists.
