Keep a clean, unluxurious lifestyle that avoids provoking social envy. Reject both vulgar overspending and stingy hoarding; aim for the balanced mean in all things. The facing Greek (p. 118) prescribes a way of life (*diaitan*) that is *kathareion* (clean/pure) and *athrypton* (unbroken by luxury, austere), while warning the initiate to guard against actions that incur *phthonos*—malicious social envy. In Greek polis life, ostentatious spending (*dapanan para kairon*, spending out of season like someone ignorant of the noble) provokes the resentment of the community; conversely, being *aneleutheros* (illiberal, stingy, servile) invites contempt and social friction. D'Olivet's French synthesis ("Luxury and avarice have similar results") captures the symmetrical trap: both extremes destabilize your social standing and corrupt your relationship to material goods. The concluding axiom—*metron d' epi pasin ariston* ("measure in all things is best")—establishes the Pythagorean mathematical mean as the law of economic and social survival. [INTERPRETATION: PRISCA THEOLOGIA / ESOTERIC] In the esoteric tradition, *phthonos* (envy) is not merely a social annoyance; it is an active psychic toxin—the *fascinum* or Evil Eye. Renaissance treatises on natural magic (including Ficino and Agrippa) explained that envious gazes project poisoned visual rays (*spiritus*) that can physically sicken the target or disrupt delicate theurgic operations. By adopting a lifestyle that is immaculately clean (*kathareios*) yet externally modest and unostentatious, the Pythagorean adept practices **social camouflage**. Walking the golden mean deflects the envious gaze of the crowd, allowing the initiate to work in undisturbed peace.
