02Browse By Format

Two formats, one learning unit.

The books — the curriculum.

Each level's complete text — the knowledge, the worked examples, and the standard of evidence. Read in the protected browser reader, licensed to you, watermarked, with your position kept between sessions.

The courses — the guided path.

Guided sessions built from the book — structured weeks, knowledge checks in every session, and capstone work, for independent study or facilitated groups. Course 1 is bundled with Book 1 at launch ($49 one-time — not separately priced); Courses 2–6 are announced with their releases.

03Browse By Topic

Follow a thread across levels.

Four threads drawn from the books' own subtitles and structures. Each chip names the angle that level contributes — and links to its page.

04Still Deciding

Let the questions guide you.

Four short questions about your experience and goals — matched against the six levels as a starting suggestion, not a placement exam.
