The ancient Indian gāthā - a proverbial, succinct type of single-stanza poetry, often collected in thematic sets - became a favoured form of expression among groups of ascetics from the middle to the end of the first millennium BCE. This poetry - contrasting with the magico-ritual chant or mantra of the priest and the artistic poem of the aesthete - functions as (self-)instruction for the ascetic/renouncer. Examples include gāthās that exhort him to be as untiring as the Sun in its daily course, or to "wander alone like the rhinoceros". This chapter delineates the figure of the solitary, wandering renouncer in a selection of Brahmanic, Jaina, and Buddhist ascetic gāthā-verses from that period. Particular attention is given to the use of solar and heroic imagery for describing the ideal renouncer, and how this relates to the real-life conditions of wandering renouncers.
