This manuscript describes the time when the Buddha went to teach Abhidhamma (The basket of higher teaching) such as Dhammasaṅgiṇī, Vibhaṅga, Dhātukathā, Pukkalapaññatti, Kathāvatthu, Yamaka, and Mahāpaṭṭhāna, to his divine mother in the Dusita heaven.
Colophon:
[The writing of this manuscript] was completed on the seventh waning-moon day of the twelfth [lunar] month, a Tuesday, a ruang met day as the Tai say, at the time of the forenoon horn, CS 1281, a kat met year. Monk Sīvijaya wrote this manuscript with his own hands so that the life of Buddhism could be prolonged 5,000 years or as long as the life of this manuscript could be. I truly wish to attain the Nibbāna. May I achieve this goal. The mistakes of missing, exceeding, and Pali mistakes just follow the original version I used. Monks who use this manuscript for sermons are invited to correct the mistakes.
