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:
การวงสามเณรเขียนแลเจ้าเอิย ตัวบ่อเสมิอ เหตวาข้าเฝิกใหม่แลเจ้าเฮิย บ่ชะนานเท่าใดแล ฯ
Sāmaṇera (novice) Karawong was the copyist. The handwriting is unorganized since I have recently learnt to inscribe palm-leaf manuscripts.
