Purpose is not something we find.

It is the direction through which energy moves, and life sustains itself over time.

We tend to think of purpose as something aspirational.

A goal.

An achievement.

But in practice, it is something else. It is functional.

Through direction, desire and engagement, purpose shapes how the system uses its energy.

When this direction is aligned, energy flows.

When it is not, it is forced.

The essays in this section explore how purpose directs a life,

and what happens when that direction is lost or found.
