Dīghanikāya

Also called Dīghāgama or Dīghasangaha.

It forms the first book of the Sutta Pitaka and consists of thirty-four long suttas, divided into three vaggas -

1. the Sīlakkhandha,

2. the Mahāvagga and

3. the Pātheya or Pātikavagga.

Buddhaghosa wrote a commentary on the work called the Sumangala-Vilāsinī.
