This text was thought to be lost, but according to Hayashiya it is included in T150A 七處三觀經. He does not show any argument to support the claim, just refers to his own article for details: Hayashiya Tomojirō 林屋友次郎, “An Seikō yaku no Zō-agon to Zōichi-agon 安世高訳の雑阿含と増一阿含,” Bukkyō kenkyū 仏教研究 1, no. 2 (1937): 11-50.
