The Kālakācārya-kathā – Story of the religious teacher Kālaka – emphasises the connection between religious practice and magical abilities. As an accomplished Jain teacher, Kālaka can master various magical sciences and transmute brick into gold. He uses his powers to help the Śakas, a foreign population. In exchange, the Śakas help him destroy the wicked king, Gardabhilla.

This eventful tale belongs to the Śvetāmbara Jain tradition. It is known in several versions in various languages and is often illustrated.

The story is frequently found as an appendix to the Kalpa-sūtra because the last part of the story explains how Kālaka changed the date of Paryuṣaṇ. This annual festival was moved from the fifth day of the bright half of the month Bhādrapada – roughly equivalent to August to September – to the fourth. The Kalpa-sūtra has a central role in Paryuṣaṇ.

The version of the story here is that of Bhāvadeva-sūri, a Śvetāmbara author of the 13th century CE. It is written in Jaina Māhārāṣṭrī Prakrit and represents a short recension, where the story is told in simple language without poetical embellishments.

This manuscript, designated as ‘r’, is one of those used by W. Norman Brown for his 1933 critical edition of this version of the story (87–92).
