Short answer: Jainism is largely aniconic (icon-free) in its spiritual focus, but it does use images in practice.

• What that means: Jains generally do not worship formless “gods” or believe in icons as deities. Devotion is directed toward the liberated souls (arhants) and the teachings, not toward the images themselves.
• Temples and icons: In many Jain temples you will see statues or images of Tirthankaras (enlightened teachers) used as focal points for meditation and reverence. These statues are aids for contemplation, not objects of worship in the sense of idolizing a god.
• Digambar vs. Shwetambar differences:

- Digambar: Tirthankaras are often depicted nude, reflecting their renunciation. - Shwetambar: Tirthankaras are typically depicted clothed in simple robes.

• Universal symbols: Jains also use symbols (like the hand with a wheel or swastika) to represent key concepts such as Ahimsa and fortune, but these are symbols of principles, not idols of gods.

If you’d like, I can give a simple example of how a particular Tirthankara image is used in Jain meditation or ritual, in a way that's faithful to Jain tradition.
