Change

Change is constant - it is the only constant.

A cliche - but a true one nevertheless:
the only thing that does not change is change itself.

All manifest reality is part of an ongoing dynamic.
There is nothing static, only flux and change.

Heraclitus - "you cannot step into the same rive twice"
Guatama Buddha - "all compounded things are impermannent"
The I Ching - the Manual of Changes

Change is movement through time.
Time is a succession of Changes.

Change means transformation, because when things change they change into something else.  They are transformed.  The new being replaces the old.

Transformation moving in a single direction is evolution - it is a continued series of changes along the same theme.
