This manuscript describes the time when the Buddha went to teach Abhidhamma (The basket of higher teaching) to his divine mother in the Dusita heaven.
Colophon:
ปริปุณณะยามกองงายแก่ข้าแล ฯ ตัวบ่งามสักคาย บ่ช่างแต้มลานใต้แลเจ้าเอิย อภิธัมมาปิฏกะ ฯ
I finished copying [this manuscript] in late morning. The handwriting is not beautiful because I am not good at inscribing palm-leafs.
