Colophon:
Folio 81 on the rect side: In Culasakkarat 1 hundred and six (corresponding with CS 1160), a poek sanga year, on the fourth waxing day of the seventh [lunar] month, Sunday, a hap sai day, the writing [of this manuscript] was finished at the time of the forenoon horn (between 9.00-10.30 o’clock). Phaya Sinòrakhut and his wife, children and all relatives had the ardent religious faith to sponsor the making of this manuscript-bundle entitled Kutthaka sikkha to support the Teachings of the Buddha to last until the end of 5000 years. May all our wishes come true, definitely. May we meet the next Buddha named Pha Ariya Mettaya (Maitreya) who will emerge in the future. May my wishes come true in the future definitely. Nibbānaṃ paramaṃ sukhaṃ (Nirvāna is the greatest bliss).
