Here are simple Jain-friendly girl names that start with D, along with brief meanings. Many of these are commonly used in Jain and broader Indian contexts.

• Diksha: renunciation; initiation (a key Jain practice of taking vows)
• Dikshita: one who has taken Diksha; initiated
• Dharini: holder, bearer; supporter
• Divya: divine, sacred
• Deepa: lamp; light (often used in Jain prayers as a symbol of enlightenment)
• Deepali: a row of lamps; a festival of lights (often used in Jain/Indian contexts)
• Disha: direction or guidance
• Drishti: sight, vision
• Dhyani: meditative, contemplative
• Dhanvi: wealthy, prosperous
• Dhriti: courage, resolve
• Dhvani: sound, voice
• Dimple: (a common affectionate name; included for modern usage)

Note:

• Many of these names are common in Jain families but are not exclusive to Jain Dharma; they are widely used in Hindu and Jain cultures as well.
• If you want Jain-specific meanings or prefer names tied to particular Jain concepts (like ahimsa, tapasya, or tirthankar-related themes), tell me and I can tailor the list accordingly.
