The Ox is Thought. Man, rule thy Thought! How else shalt thou master the Holy Spirit, and answer the High Priestess in the Middle Gateway of the Crown?
Here are practices. Each may last for a week or more.
Avoid thinking of a definite subject and all things connected with it, and let that subject be one which commonly occupies much of thy thought, being frequently stimulated by sense-perceptions or the conversation of others.
By some device, such as the changing of thy ring from one finger to another, create in thyself two personalities, the thoughts of one being within entirely different limits from that of the other, the common ground being the necessities of life.
Of thine own Ingenium devise others.
On each occasion that thou art betrayed into thinking that thou art sworn to avoid, cut thyself sharply upon the wrist or forearm with a razor; even as thou shouldst beat a disobedient dog. Feareth not the Ox the Goad of the Ploughman?
Thine arm then serveth thee both for a warning and for a record. Thou shalt write down thy daily progress in these practices, until thou art perfectly vigilant at all times over the least thought that ariseth in thy brain.
Thus bind thyself, and thou shalt be for ever free.
 For instance, let A be a man of strong passions, skilled in the Holy Qabalah, a vegetarian, and a keen "reactionary" politician. Let B be a bloodless and ascetic thinker, occupied with business and family cares, an eater of meat, and a keen progressive politician. Let no thought proper to "A" arise when the ring is on the "B" finger, and vice versa.
