Answer

In Digambar Terapanth Jain tradition, generally diya (lamp) is not used in temple puja as a required ritual item.

Digambar Terapanthis usually emphasize simple, non-possessive, and less material-based worship, so their temple worship commonly avoids items like:

• Diya / deepak
• Aarti with flame
• Decorative or elaborate ritual offerings

Explanation

Digambar Terapanth tradition arose as a reform movement within Digambar Jainism. It placed strong emphasis on worship that is:

• Simple
• Scripture-based
• Free from unnecessary ritual display
• Focused on inner devotion and right faith

So, in many Digambar Terapanth temples, instead of lighting a diya or doing flame-based aarti, devotees focus on:

• Darshan
• Namokar Mantra
• Abhishek
• Puja with limited traditional dravyas, depending on local practice
• Stavan, path, and meditation

Important Note

Practices can vary slightly by region, temple, and local sangh. Some families may light a diya at home out of personal habit or cultural influence, but strict Digambar Terapanth temple practice generally avoids diya/aarti with flame.

Takeaway

For Digambar Terapanthi Jains, devotion is mainly expressed through inner bhav, mantra, darshan, and simple puja, rather than lighting a diya or performing flame-based aarti.
