Interdependent elements in life are flow and structure. Both are necessary.

Only structure, implies rigidity.

 Only flow, implies chaos.

The functional coexistence of the two requires the existence of measure.

The phrase of Heraclitus is shocking: Flowing in the building and building in the flow.

The constant combination of flow and structure, their constant interplay is required in the process of psychotherapy as it follows the rules with discipline, but has the freedom to individualize, become unique, when approaching each unique person.
