Day one hundred and sixty-three. Sunday. July 12. PRIME

Interior of a small stone cottage on SUNDAY, July 12 — TWENTY-ONE DAYS past the summer solstice (21 = 3 × 7, the PATTERN times the WEEK-LENGTH, exactly THREE WEEKS of declining light, the recession at the cleanest temporal unit — three complete weeks, the retreat measured in the pattern-number of full weeks; still overwhelmingly summer, the thermal lag at its absolute peak, July heat at maximum, the air thick with stored solstice energy, but the light declining by three full weeks now, the decline PROVEN, established, certain), SUNDAY — the SEVENTH day of the week, the WEEK-LENGTH day, the day that NAMES the week itself, the day of DEEPEST REST, the Sabbath, the day beyond the work week and beyond Saturday's first leisure, the most settled day, the stillest day. Day 163 = PRIME — the 38th prime (38 = 2 × 19), the age IRREDUCIBLE, indivisible, atomic, the age admitting NO factors, the most fundamental form, the age at its simplest possible identity. This is the PATTERN — the THIRD mark of row thirty-three = 3 × 11, the PATTERN-NUMBER times ELEVEN — the mark of CERTAINTY, of PROOF, of settled conviction that the row will continue. The PATTERN in the PATTERN'S OWN ROW — mark three in the row of three-times-eleven, the proof arriving at the house of the proof, the certainty entering the domain of certainty. 3 × 33 = 99 = 3² × 11 — the mark-row product at the PATTERN-SQUARED times ELEVEN, one less than one hundred, the boundary of magnitude. The pattern drawn in the DEEPEST QUIET — twelve or more days of solitary practice, past the calendar-number, the creature alone for the temporal equivalent of a year measured in days. The pattern as AUTONOMOUS PROOF — the certainty generated without witness, the self-sustaining evidence of continuation, the third mark in solitude saying: the practice does not need witnesses to be certain.
