Pusaka is a Sanskrit word meaning treasure or heirloom.
In Javanese Kejawen culture and the Austronesian cultures affected by it, known as the Malays, but most specifically the inhabitants of modern day Indonesia and Malaysia; (Minangs), Balinese Bataks, Bugis, Manado, Minang, Moro, Pampangan, Taglog and many others- pusaka specifically refers to the family heirlooms gifted from the ancestors which must be treasured and protected. These pusaka may have individual names, honorific titles and may have supernatural attributes and qualities. The possessor of the pusaka may be positively or negatively affected by the pusaka- dependent on the will or spirit of the item.
The Javanese warrior-king Pangeran Samburnyowo's keris was a pusaka so powerful that merely pointing at the distant Chinese, Dutch or other enemies, it would snatch their souls and leave them dead on the battlefield. Allegedly, former Indonesian President Suharto held possession of this powerful pusaka and had Indonesia scoured for the many pusaka lost to time, including, according to rumours, the mask of Gadjah Mada, several tombak (pikes and lances) and many keris, to affirm his legitimacy as a modern pseudo-king.
