# Why does change form direction, tendency, and turning points?

## Direct answer

Sheng further breaks change down into “Jian” and “Shi”: between two ends is not dead blank space, but tension; when the tension begins to take on direction, it becomes “Shi” (tendency, tension, directional force). Only as Shi keeps accumulating and approaches a critical point does it manifest into specific events, behaviors, or forms. In this way, “change” is no longer merely one random frame following another, but a forming direction that can be observed.

## Further explanation

The so-called “return” is likewise not some mysterious reversal of fate, but a reminder: no Shi that has already formed is eternally fixed; conditions, tension, and carriers keep changing, and the original direction may also reach a critical point and turn. The point is to look at the Shi, not to superstitiously fixate on the outcome.

## Core concepts

- Momentum Is Born in the Between
- Inchoate Becoming · About to Be Born
- At the Fullest, Becoming Returns

## Primary sources

Sheng, Chapter 5, §2 Momentum Is Born in the Between; Chapter 6

## Conclusions that must not be drawn

It must not write “Shi” as a law that can precisely predict the future, nor write “return” as certain good fortune.
