黄金刀

thumb|Phurba in the Walters Art Museum The phurba (; alternate transliterations: phurpa, phurbu, purbha, or phurpu)or kīla (Sanskrit Devanagari: कील; IAST: kīla) is a three-sided peg, stake, knife, or nail-like ritual implement deeply rooted in Indo-Tibetan Buddhism and Bön traditions. Its primary association is with the meditational deity Vajrakīlaya (Dorje Phurba), embodying the essence of transformative power. The etymology and historical context of the term reveal some debate. Both the Sanskrit word kīla and the Tibetan phurba are used interchangeably in sources.
