    The Shera Zadí Circle Codex

    What moves
    you

    Everyone carries a movement of truth. A direction that shows up before you think, and colours every beginning, every choice, every return. The Codex gives that movement a name.

    Not a personality type. A movement.

    The Circle Codex is a system of self-inquiry. It names eleven movements of truth: eleven ways a life begins, feels, builds, breaks and returns. These are not personality types like the enneagram or the MBTI. They are movements, directions of energy that were already at work in you long before you had words for them.

    Recognition, not belief

    You don't have to believe anything. You only have to recognise: yes, that is how I move.

    One of eleven

    You carry all eleven movements. But one is dominant, and it shapes how you meet the world.

    Already in motion

    Your movement was there before you read a word. The Codex simply gives it a name.

    The eleven movements.

    Eleven ways truth moves through a life. One of them is yours.

    Who is
    Shera Zadí?

    Shera Zadí is not a historical person. She is a lens, a voice, a way of bringing old insight to life.

    In the tradition at the heart of the Codex, she was a woman who listened long enough in the desert to feel the pattern beneath every life, and named it in eleven movements. Through her stories and the fragments her students kept, the system unfolds as a living philosophy. The work is by Arjan Duijs, published by Black Dunes Press.

    Stay close to the work.

    A quiet letter now and then: new readings, notes on the Circles, and when the fuller work arrives.
