Yes. In Jainism, the signs (lanchhan) of the Tirthankaras convey meaningful, doctrinal ideas and help us recognize and remember each Tirthankar’s teachings and path.

Key points:

• Each Tirthankar has a unique emblem or symbol that appears in temples, paintings, and calendars. These emblems are not physical signs from the past but symbolic representations of their life and spiritual achievement.
• The lanchhan helps devotees identify the Tirthankar and understands aspects of their example (renunciation, austerity, compassion, spiritual knowledge).
• There are differences in how symbols are depicted or emphasized in Digambar and Shwetambar traditions. In some cases the same Tirthankar may be shown with slightly different iconographic details, but the underlying symbol remains recognizable in both traditions.
• The symbols are used to teach and memorize the Jain path: right faith, right knowledge, and right conduct, as exemplified by each Tirthankar.

If you’d like, I can summarize the lanchhan for each of the 24 Tirthankaras and note where Digambar and Shwetambar traditions differ.
