Earth light — secret centre
Yellow stabilising element
The lower anchor represents the earth element in a fivefold light-body presentation and is placed at the secret or root region for visual continuity with Tibetan completion-stage maps. This is a subtle-body convention with broad uncertainty, not a claim that a Dzogchen tantra identifies a single gross anatomical earth centre.
