Ningishzida — "Lord of the Good Tree," Sumerian god of the underworld and healing — is shown as two serpents intertwined around an axis. On a libation vase of Gudea (c. 2100 BCE), the oldest known image of the twin-serpent staff, two millennia before the caduceus. The double helix at the root of the healing professions — and, the canon may whisper, of life's own code.
The SGE Reading
Gift stage as *anatomy of medicine*: the healer's oldest symbol is the balance of two currents around a central axis. The same image is the caduceus, ida-and-pingala around the sushumna, and the DNA helix.
Canon Resonance
Bridge between the Mesopotamian and Indian layers of the saga — one image, five thousand years.
A Micro-Practice
Sit tall. Feel breath rising on the right, falling on the left, around the central line of the spine. This is Ningishzida's vase, drawn in your own body.
