Groups of three Phases, which together form a single gyre, in which form they tend to be used in Yeats's treatment of history. Except for the four Cardinal Phases, each Phase falls within a triad. The first Phase of triad is the Manifestion of an energy, often violent or anarchic; the second Phase is the Organisation of that energy, which codifies and arranges the powers involved; the third Phase is the Preparation for arrival of the next energy, showing a belief in, appreciation of or submission to that quality (see AV B 93). See The Cardinal Phases and the Triads.
