Wadian Dadas is a dance danced by wadian (shaman) to cure illnesses in the Dayak indigenous people. This study aims to find out the philosophy contained in the Wadian Dadas; including forms of the ritual and the preservation of the dance. Based on the results of the study, we found that the Wadian Dadas contains mysticism because there is a ceremonial ritual before the implementation of the dance. In the Wadian Dadas, there is a philosophy of devotion to the Almighty (Hiyang Piumung) which is symbolized by an Eagle in Ma'anyan and known as management. The meaning of local wisdom is that this dance is a way to find Ineh Payung Gunting that gets inspiration during hermitage, in order to cure illness. This dance is inherited from generation to generation. The form of Wadian Dadas ritual consists of preparation in the form of fulfillment of offerings, reading incantations and swinging bahalai. The effort to preserve the Wadian Dadas is performed by performing a dance at ceremonies of legal treatment for Ma'anyan Dayak marriage and is held at the time of the grand reception. From the results of this study, it can be concluded that the Wadian Dadas that grows and develops among the Ma'anyan Dayak indigenous people was originally a regional dance that has cultural values and contains magical elements.
