This volume brings together Bhikkhu Anālayo's studies of the Dīrgha-āgama, the Chinese counterpart to the Dīgha-nikāya's collection of long discourses. Alongside translations and comparative discussions of individual discourses – including the Brahmajāla, the Buddha's last days in the Mahāparinibbāna-sutta, Sakka's questions, the tale of King Pāyāsi, the wheel-turning monarch, and the numerically arranged Dasuttara-sutta – the volume opens with a broader examination of the collection's earliest material, and closes with three chapters exploring how features of oral transmission shaped the surviving texts.
