Level 26: Marrow

Classical "marrow washing".

reconstructed Status Drawn from classical neidan by this archive, to show the shape of the band. Time in grade Unfixed. This is the passage the classical sources describe as long, undramatic and impossible to hurry, and the one Mo Pai's own accounts also treat as the longest. Body map The dan tien and the gates

Description

Classical "marrow washing". The deep tissues are said to be reached for the first time.

This entry is a reconstruction. Mo Pai publishes no curriculum for level 26, so what appears above is drawn from the classical stage this band corresponds to — the body-refining register of lian qi hua shen — the "washing" and "changing" literature — and from the shape the Mo Pai literature implies for the "Purification of the Vessel" band. It is a map of the territory that tradition describes, written by this archive and not taken from the lineage.

Practice

Reconstructed from xi sui jing material — "washing the marrow". The classical claim is precise: refined qi is said to reach the marrow before it reaches anything else deep, and the practice is unchanged sitting held until it does. The associated text has a long attribution to Bodhidharma that no historian accepts.

Signs and effects

The deep tissues are said to be reached for the first time.

How it is tested

Not published. Teacher-verified, as at every level below — and unverifiable here in a second sense, since the classical account below is not Mo Pai's.

Obstacles

The attribution problem, which is worth knowing before reading anything sold under this name: the surviving marrow-washing literature is late, and the arts taught under it today are mostly reconstructions themselves.
