INTRODUCTION

English translation pending.

CORE DEFINITION

Sea of Marrow comes from the Huangdi Neijing, which states that the brain is the sea of marrow. The kidney stores essence and generates marrow, which rises to fill the brain, so cognitive function tracks the fullness of kidney essence and marrow. The qualifier is that the doctrine is a model of resource supply rather than a claim about anatomy. When the sea is insufficient, the classical signs are dizziness, tinnitus, aching shins, and clouded vision, all read as a thin medium rather than as damage to the organ itself.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Supply framing: Read mental fatigue as a resource problem, not a willpower problem. - Coolant metaphor: Treat marrow as the medium the thinking organ floats in. - Root maintenance: Service the source of supply instead of pushing the output.

Anchor fast decisions

The brain is modeled as an organ suspended in a fluid medium that must be replenished from a deeper store. When the store runs low, the medium thins and processing degrades into dizziness, forgetfulness, and dullness. Maintaining the source therefore maintains the output, which is why the therapy targets essence-filling rather than the head itself.

Glass Walls

Distinct from the 'glass ceiling' (vertical promotion barrier), it refers to women or minority groups being isolated in certain functional departments (e.g., HR, administration), making it difficult to move laterally to core business departments (e.g., sales, R&D), thereby lacking the key experience needed for promotion.

Inertia

Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its velocity to change. It is one of the fundamental principles in classical physics, and is described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). It is one of the primary manifestations of mass, one of the core quantitative properties of physical systems.
