Sutra

Sutra (Sanskrit: सूत्र) means thread or string, from the root siv (to sew)[1]. The literal sense is that a sutra threads together teachings into a compact form. In Hindu use, sutras are typically very compressed aphoristic texts (Patanjali's Yoga Sutras, the Brahma Sutras). In Buddhist use, sutra refers to longer discourses attributed to the Buddha[2]. The Pali equivalent is sutta.

the word is used across traditions, so context matters when identifying which canon is in view.

In Hindu tradition, sutras are concise philosophical and ritual texts. Major examples include the Yoga Sutras of Patanjali (systematizing yoga practice), the Brahma Sutras (organizing Vedantic philosophy), the Nyaya Sutras (logic), the Vaisheshika Sutras (atomism), the Samkhya Sutras (dualistic enumeration), and the Mimamsa Sutras (ritual interpretation). The texts are typically so compressed that they require commentary to be understood; long commentary traditions (bhashya) have developed around each major sutra collection.

In Buddhist tradition, sutras (sutta in Pali) are discourses attributed to the Buddha, typically presenting his teaching in conversational or expository form. The Pali Canon's Sutta Pitaka contains thousands of suttas organized into five major collections (nikayas): the Digha Nikaya (long discourses), Majjhima Nikaya (middle-length discourses), Samyutta Nikaya (connected discourses), Anguttara Nikaya (numerical discourses), and Khuddaka Nikaya (minor collection).

Mahayana sutras include major texts not in the Pali Canon: the Prajnaparamita literature, the Lotus Sutra, the Avatamsaka Sutra, the Lankavatara Sutra, the Vimalakirti Sutra, the Heart Sutra, the Diamond Sutra, and many others. These are typically attributed to the Buddha while having emerged historically later than the Pali corpus. The Mahayana tradition holds these sutras as authentic Buddhist teaching that became available at the right time.

Different Buddhist schools privilege different sutras. The Pali Canon is foundational for Theravada[2]. Various Mahayana schools center on specific sutras: the Lotus Sutra for Tiantai and Nichiren, the Heart Sutra and Diamond Sutra across Zen, the Pure Land sutras for Pure Land traditions[3]. Studying, reciting, and copying sutras has been central religious practice across Buddhist traditions.

Sutra studies is a major area in Hindu and Buddhist scholarship. Indological work on the major Hindu sutras and their commentaries fills extensive libraries[4]. Buddhist sutra scholarship includes the Pali Text Society's editions and translations, modern academic work by figures including Jonathan Silk, Jan Nattier, and many others on Mahayana sources.
