In Jainism, "Ajit Bal Devi" refers to a specific protective goddess (Yakshini) associated with Lord Ajitnath, who is the second Tirthankara. Each Tirthankara in Jainism is believed to have a Yaksha and a Yakshini (attendant deities) who serve as guardians or protectors of their images and teachings.

Ajit Bal Devi (sometimes also called "Ajita Yakshini" or "Ajit Yakshini") is revered by some Jain communities as the Yakshini of Lord Ajitnath. She is often depicted in Jain iconography and temple art, usually shown seated on a lotus and sometimes with specific attributes in her hands. Devotees may offer prayers to her for protection and blessings, especially when venerating Lord Ajitnath.

It's important to note that worship of Yakshas and Yakshinis is more prominent in the Śvetāmbara Jain tradition, and their significance is secondary to the veneration of the Tirthankaras themselves. The primary focus in Jainism remains on the path of non-violence, self-discipline, and liberation (moksha), with Yakshas and Yakshinis serving a supplementary devotional role.
