The Kalpa-sūtra is the most frequently illustrated Jain text of the Śvetāmbara sect. It is read and recited by monks in the Śvetāmbara festival of Paryuṣaṇ, which takes place in August to September each year.

The first part of the Kalpa-sūtra deals with the lives of the Jinas, especially Mahāvīra, Pārśva, Nemi and Ṛṣabha. It features almost identical stories of their births, lives as princes, renunciation, enlightenment and final emancipation.The second part – Sthavirāvali – is a praise of the early teachers of Jainism. The third part – Sāmācārī – deals with particular monastic rules to be followed during the rainy season.

The author, or authors, of the Kalpa-sūtra is unknown, although it is attributed to Bhadrabāhu. Manuscripts of the Kalpa-sūtra frequently contain a related text at the end, called the Kālakācārya-kathā. The Story of the Monk Kalaka provides an explanation of the date of the festival of Paryuṣaṇ, in which the Kalpa-sūtra features. The version in this manuscript is by Bhavadeva-sūri.
