Neminath (Nemi) and Rajul (Rajulakumari/Rājulā Devi) are described as fiancé and bride in Jain tradition. Here is the core relation history in simple terms:

• Who they are: Rajul is said to be the daughter of King Ugrasena and the betrothed of Neminath, the 22nd Tirthankara. This marriage arrangement is part of Jain legends about Nemi’s life before renunciation. ( jainknowledge.com)
• The turning moment: On the day of the wedding, Neminath hears the cries of animals that are to be slaughtered for the feast. This moved him to renounce worldly life and become a monk. Rajul is described as following him, choosing the path of renunciation herself. This moment is a key part of their shared story. ( jainknowledge.com)
• After renunciation: Neminath and Rajul both take Diksha (renunciation). In many tellings, they spend their lives in intense ascetic practice together, with Rajul becoming a respected sadhvi (nun). The exact details of their later spiritual fate differ by tradition. ( jainknowledge.com)
• Differences between Digambara and Śvetāmbara:

- In Śvetāmbara accounts, Rajul and Neminath are said to attain moksha on the same day or in closely tied final events. - In many Digambara versions, Rajul is remembered as a celebrated sadhvi who ultimately attains moksha separately, sometimes at Girnar or in a closely linked spiritual lineage. The emphasis is still on her fidelity, chastity, and renunciation. ( jainknowledge.com)
