"The so-called kabala is the human skull; the so-called basuda is the human internal organs that have been taken out; the so-called gangling is the trumpet made of human tibia; the so-called xinggeyangxi is a piece of human skin spread out; the so-called lokto is the blood sprinkled on the offering; the so-called mandala is a group of rainbow-like colors; the so-called vajra is a person with a flower vine made of human bones." - Trisong Detsen's concubine Tsai Bangshi
