‘The dialogue between a cat and a mouse’ (Mārjāramūṣakasaṃvāda) is an animal fable used in the Mahābhārata to provide instruction in statecraft (nīti). This article argues that the Mahābhārata version of this tale must be based on an earlier soteriological allegory about a brahmin who provides spiritual liberation to a king in exchange for protection. The Mārjāramūṣakasaṃvāda abounds in terms and phrases that, in addition to their everyday meanings, have a technical or typical usage in the ascetic traditions of Ancient India. Moreover, the conversation between the cat and the mouse resembles that between a teacher and a disciple, rather than a discussion of a possible alliance between two kings. The hunter of the Mārjāramūṣakasaṃvāda can be identified with the Buddhist Māra. To support the plausibility of this soteriological reading, the article includes a discussion of Buddhist jātakas with a similar plot.
