The Mūlasarvāstivādin tradition grouped the Buddha’s early sūtra discourses into four divisions, or āgama (Tib. mdo sde’i lung sde bzhi): the Dīrghāgama (Tib. lung ring po), the Madhyamāgama (Tib. lung bar ma), the Ekottarikāgama (Tib. lung gcig las ’phros pa), and the Saṃyuktāgama (Tib. lung dag ldan/yang dar par ldan pa’i lung). They are more familiar to many English-speaking Buddhists through the translations of their Pali correlates: the Dīgha Nikāya, Majjhima Nikāya, Aṅguttara Nikāya, and the Samyutta Nikāya, for which see the Wisdom Publications titles: The Long Discourses of the Buddha, The Middle-Length Discourses of the Buddha, The Numerical Discourses of the Buddha, and The Connected Discourses of the Buddha, respectively.
