When you mention mitsung or "Tantric Buddhism," some people think of geomancy, a wheel of mantra, various types of mudra, a ring on which secret mudras were inscribed, or rosaries carved from lamas 'skulls. Or perhaps it's the mandala prohibited to outsiders--in which are enshrined not only the commonly seen Bodhisattvas, but also the various awe-inspiring Dharma Protectors and other wrathful deities.
說起密宗，有的人會想到風水、咒輪；有的人會想到刻有密咒的戒指，由喇嘛頭蓋骨雕成的念珠、莫測高深的各式「手印」，或是謝絕外人參觀的密壇﹘﹘上面不僅供著一般常見的、莊嚴慈悲的佛菩薩，還供著忿怒威猛，令人望而生畏的金剛、護法等。
