# DNA

> A Mind's permanent personality, values, and operating principles.

DNA is a Mind's permanent personality, values, and operating principles. It is part of the [Soul](/docs/concepts/soul) and shapes how the Mind approaches every task.

As the [Steward](/docs/concepts/steward), you define DNA during setup in your Minds account or through your integration. DNA is not wiped when the [Brain](/docs/concepts/brain) model changes; only reasoning quality improves.
