The development of philoshopy in Java begins with the question of who he really is (sapa ingsun), who is his God (sapa Gustiningsun), where he came from and where to return (sangkan paraning dumadi), and also how to achieve union with God (manunggaling kawula Gusti). Javanese people can be said as a religious people. This can be seen from the understanding of Javanese people towards the reality of the self dan the world as a full of mystery and in an effort to obtain the truth, the Javanese people prefer to reflect inside to the self. If philosophy in general is a search for wisdom however the Javanese society philosophy is an attempt to achieve the union with the Supreme Being.
