An Introduction
Once upon a time there lived a prince called Siddhartha. One day he went to royal garden. By the way he sees a dead body accompanying suffering relatives. Then he start to think deeply about suffering. why i don't feel suffer, why only they suffer, because if bondage then only suffering arise. then he see a "Bikku" who searchers the way to illuminate bondage that create life sufferings. On his return way a lady called "KisaGothami" says "Nibbutha Gata", with that encouragement he decide to find Vimukthi or end of suffering.
So he search teachers who can show how to overcome life sufferings.
One of them teach him everything consist Four "MahaButha" (elements) so develop concentrate on it and realize only "Akasa" is. then only "Vingnana" as the reality.
Another teacher shows the person(Athma) is when only feels it. if there is not "Sagna" then no self.("Newer sangna na sagnayathanaya").
"Maha Bodhisattva" realize they are not the complete solutions for the life problem and decide to find his own path. He follows "Aththakilamathanu yoga" that popular Yoga technique. After about six years he give up it and follows his own experience at his very young age - Anapanasathi. After enlightenment at first sermon teach four Noble Truths.
The point here is that phenomenal reality is projection, an interpretation that depends on the point of view. Because experienced reality is projection, we can control it by controlling our point of view.
