Explanation

On the day of his parinirvana, the Buddha reminded his disciples that the dharma teachings had been imparted in twelve aṅgas, or branches, each a means of evoking a different response and realization.

1. Sūtra. Discourses on a single topic. Seeing ten advantages of this type of teaching, the Buddha often taught in this way. Sutra teachings are well-suited for presenting a single topic; they easily evoke the listener's response, they increase respect for the dharma, supporting the rapid application of the teachings to one's life, they enable the teachings to penetrate deeply, they inspire serene joy based on faith in the Buddha, faith in the Dharma, and faith in the Sangha; they support supreme happiness even in this lifetime; they please the minds of the wise through exegesis; and they are recognized as extremely wise.
2. Geya. Discourses in verse. These are the stanzas often found at the beginning or end of a sutra. Sometimes an idea not discussed within the sutra will be explicated in verse.
3. Vyākaraṇa. Prophecies. Thse are discussions of the past lives and future possibilities of the assembly of the Sangha. They serve to clarify points presented in a sutra.
4. Gāthā. Verse summaries. These teachings are given in metred verse within sutras. They recapitulate the main themes and are easy to remember.
5. Udāna. Words spoken not to instruct particular individuals but to maintain the dharma. These teachings are said to have been spoken by the Buddha with a very joyful heart.
6. Nidāna. Explanations following a specific incident. In these teachings, the Buddha gives a principle or guideline and explains the reason for it.
7. Avadāna. Life stories of buddhas, bodhisattvas, disciples, and various individuals.
8. Itivṛttaka. Historical accounts such as geneologies.
9. Jātaka. Accounts of previous lives of the Buddha.
10. Vaipulya. Lengthy sutras with complex organisation. These include the sutras of the Mahayana, with teachings that are especially profound and vast.
11. Abidhutadharma. Accounts of wondrous accomplishments of the Buddha, the disciples, and the bodhisattvas.
12. Upadeśa. Topics of specific knowledge. These are exact, profound, and subtle instructions on the nature of reality.

Sūtra, geya, vyākaraṇa, gāthā, and udāna teachings make up the sutra collection of the First Turning. The aṅgas of vaipulya and abidhutadharma appear in the Second and Third Turning teachings. These express the extensive vision and wondrous accomplishments of the buddhas and bodhisattvas.
