Death which represents the end of life, is probably the main "culprit" why the belief in supernatural appeared among the human civilizations. Inexplicable fear from that strange condition and generally panic from disappearing caused among the people on the entire globe frustrations and eternal questions from the earliest times - why are we born and why do we die? Though we don't know the answer to this question even today, yet we as a civilization tried to fill the world with things in order to introduce some order and thereby give a certain sense to everything we do.
This is why humans invent religion, its unrestrained imagination creates a large number of imaginary beings which surround him, and despite numerous human characteristics, still they have some exaltation which separates them from the world of humans. Throughout centuries religion experiences its constant trend, upgrades, adjusts to human advancement and finally in ancient Iran it receives its present nature through dualism of Persians Manesa and the prophet Zarathustra, on whose principles monotheism is born - direction which tries to convince us in the absurd i.e. how it is possible that in the universe there are two principles - good and evil, but that only one principle is important and the second one is less important?!
Because of such an erroneous religious idea in Bosnia and Herzegovina around the tenth century, and probably even sooner, a revolutionary religious direction started to spread fast which seriously impairs the rigid Christian doctrine, it propagates that through the world, but also the universe, two equally important deities rule between which exists man and his primary spiritual mission to clean his soul from sins, and after death to return it to heaven. Such a claim is pretty rational, if we take into consideration the definition that according to the principles of quant physics all matter is actually condensed energy and that this is the reason why all of us are beings of energy or beings of light, what leads us into traditional belied in the spirit and soul, which every human possesses.
But, in order to die we must be born, feel life for at least a moment, in order for our spirit and soul to achieve a balance, since without this alignment with two universal principles, or with two deities of our forefathers Bogomils, we cannot enter the adventure called death. Folk wisdom claims that the spirit is the representative of the god of evil and the soul, pure and holly, it represents the god of good inside of us. While the spirit has the possibility to, usually at night while the man is sleeping, go out of the body and travel the world and also perform some weird, often bad things and bring us into various temptations, the soul is firmly fixed for the human body and there is no possibility of exiting it until death.
