Frequently asked

What is Lower dan tian (下丹田)?

Lower dan tian (下丹田) — the storage centre of jing (essence), located in the lower abdomen approximately three cun (a body-relative measure ~ four finger-widths) below the navel, in the region of the CV6 acupoint (qihai, 'sea of qi'). In Neidan it is the foundational reservoir from which the alchemical work begins; the first transformation of internal alchemy is jing → qi, accomplished by gathering scattered essence into this centre. The coordinate corresponds to the project's LOWER_DANTIAN landmark, calibrated against the WHO Standard Acupuncture Point Locations.

What is Middle dan tian (中丹田)?

Middle dan tian (中丹田) — the storage centre of qi (vital breath), located at the tanzhong region (CV17), at the mid-sternum between the nipples. In Neidan it is the seat of the second transformation, qi → shen: refined qi rising from the lower centre is gathered here and further refined into spirit. The coordinate corresponds to the project's STERNUM_MID landmark.

What is Upper dan tian (上丹田)?

Upper dan tian (上丹田) — the storage centre of shen (spirit), located at the brow centre (yintang region) and extending inward toward the niwan palace within the head. In Neidan it is the seat of the third transformation, shen → emptiness (xū), the final return to the originless state. The coordinate corresponds to the project's THIRD_EYE landmark. Some Daoist lineages place the upper dan tian at the crown (bai hui / DU20) rather than yintang; that variant is recorded in lineage_variants_known.
