All of our life is conditioned by our system of beliefs and some of them carry us towards fulfilment while others limit or even freeze us. In short, our reality, our world view, flows directly from our belief system.
The good news is that a belief can be transformed. The least good news – regardless of the hardcore of reason – is that the will of the conscious mind is not enough to transform a belief simply because most of them are firmly anchored in the deepest layers of our subconscious.
Some of our beliefs are rooted in the results we derive from lived experiences (both unhappy and happy) while others – those that are more difficult to transmute – come not from our personal experience but from the education received and the socio-cultural environment in which we are born and grow up.
Fan of non-ordinary psychic experiences, I personally tried the one of living without beliefs. Interesting experience with however extreme accents that I recommend to no one and whose result was that it seems impossible to live without beliefs. Moreover, when the skeptics of antiquity pretended to suspend their judgment on everything, Aristotle invited them to remind that they did not go for a walk on the edge of a precipice on a day of strong wind.
Your belief system has only a value for yourself, and if you are at peace with it, you have no need to claim it or seek external approval nor try to impose it on someone else. So… where are you on your belief system?
