Aranatha, the eighteenth Tirthankara, completes a small cluster of figures in the sequence, alongside Shantinatha and Kunthunatha immediately before him, whom Jain tradition credits with having also served as a Chakravartin, a universal temporal ruler, prior to renouncing that rule for spiritual liberation. The clustering of this dual role among three consecutive Tirthankaras is itself a notable feature of the tradition's narrative structure, suggesting a deliberate concentration of the renunciation-of-supreme-power theme at this point in the sequence rather than an even distribution of the motif across all twenty four figures.
Whatever the reason for that clustering, Aranatha's combined status again gives him somewhat richer narrative material than a figure holding only the Tirthankara role would have, since his story includes an account of temporal rule as well as spiritual teaching. As with Shantinatha and Kunthunatha, and indeed with all the Tirthankaras earlier than Parshvanatha and Mahavira, this material sits within Jain cosmology's vast internal chronology rather than within any period historians have a method for testing, and its significance for the tradition lies in its doctrinal illustration of renunciation rather than in any independently verifiable historical claim about a datable emperor.
