In a Jain house of mourning, it is generally better not to bring candles, unless the family specifically requests them.

A more Jain-appropriate gesture is:

• simple, quiet presence
• flowers only if the family permits
• a plain card or respectful message
• avoiding anything that involves unnecessary harm, strong fragrance, or ritual that the family may not observe

Because Jain tradition emphasizes ahimsa, simplicity, and restraint, the safest choice is to keep your offering minimal and respectful. If you are unsure, come empty-handed and offer your condolences sincerely.
