In Digambar Jainism, Ganeshji (Vinayak) is not a Tirthankar or a Jina. He is generally not part of the core Jain path, which centers on the twenty-four Tirthankaras. However, in some Digambar temples and local practices, Ganesh is revered as a guardian deity (yaksha) or as part of devotional rituals. This is a regional or sectarian usage and not universal across all Digambar communities. There are also differences between Digambar and Shwetambar traditions in how Ganesh is viewed or worshipped.

If you’d like, I can share a simple, authentic Jain explanation of how yakshas/yakshinis relate to Tirthankaras and where Ganesh fits in some Digambar practices, or point you to a JainKnowledge.com page for more detail.
