The manuscript No.50B is written in a notebook with blue cover. The size is 21 x 16.5 cm. The condition of paper is brittle and yellowing. The writing is still readable. In this manuscript, Prince Madrais describes his teachings. If we know and do all the words written in the book of Pusaka Jawa, we certain that is the words of God; The Guru of all souls which fuse with the body in the past and now. The true God is Guruning Ratu Panatagama who created darkness and brightness. If you can see clearly at the darkness and brightness, you will know how to act in the world. When the time comes, the promise will be fulfilled. The fact will show the falsity and lie that were spoken by the evil forces. They humiliated Madrais and mocked him with the bad words. Although, he was regarded as an infidel, he did not care. Something is wrong with Java custom. The evil forces were false. They felt as if the holiest on and reserved the right to get heaven.
