Mamukur is one of the pitra yadnya ceremonies that aims to purify the atma so that it is released from the subtle body (suksma sarira), namely in the form of human traits and desires, so that they can unite with the creator to become the god pitara (holy spirit).
Mamukur wantah silih tunggil upacara pitra yadnya sane matetujon mangdane prasida nyuciang atma raris prasida lepas saking suksma sarirannyane, inggih punika prasida ngicalang sakancan sane kaon raris manunggal ring ida sang hyang widhi raris manados pitara.
