Some of the most commonly referenced suttas from the Digha Nikaya include the Mahāparinibbāṇa Sutta (DN 16), which describes the final days and passing of the Buddha, the Sigālovāda Sutta (DN 31) in which the Buddha discusses ethics and practices for lay followers, and the Samaññaphala Sutta (DN 2) and Brahmajāla Sutta (DN 1) which describe and compare the point of view of the Buddha and other ascetics in India about the universe and time (past, present, and future); and the Poṭṭhapāda (DN 9) Sutta, which describes the benefits and practice of Samatha meditation.
The Digha Nikaya consists of 34[1] discourses, broken into three groups: The Digha Nikaya corresponds to the Dīrgha Āgama found in the Sutta Piṭakas of various Sanskritic early Buddhist schools, fragments of which survive in Sanskrit.
A complete version of the Dīrgha Āgama of the Dharmagupta school survives in Chinese translation by the name Zhǎng Āhánjīng (長阿含經).
It contains 30 sūtras in contrast to the 34 suttas of the Theravadin Dīgha Nikāya.
In addition, portions of the Sarvāstivādin school's Dīrgha Āgama survive in Sanskrit and in Tibetan translation.
