Five Āgamas (五阿含). An Āgama is a collection of early Buddhist scriptures.
the Five Āgamas in the Chinese Canon are
the Dīrgha Āgama (long discourses),
the Madhyama Āgama (middle-length discourses),
the Saṁyukta Āgama (connected discourses),
the Ekottarika Āgama (discourses ordered by the number of Dharmas in each discourse), and
the Kṣudraka Āgama (minor discourses).
They are parallel but not identical to the Five Nikāyas in the Pāli Canon, which are the
the Majjhima Nikāya,
the Saṁyutta Nikāya,
the Aṅguttara Nikāya,
and the Khuddaka Nikāya.
