In myth, Kunlun is the pillar joining earth to heaven, the residence of Xiwangmu, the Queen Mother of the West, and the garden where the peaches of immortality ripen on a schedule of millennia. It is the destination of visionary journeys throughout the early literature.
There is also a real Kunlun — a genuine range along the northern edge of the Tibetan plateau — and the myth is not about it in any useful sense. The name was borrowed in the 2000s by a modern internal system taught in the West, which is how it enters this archive.
