Here are some Jain-friendly boy names starting with “D” and their simple meanings:

1. Dharmesh – Lord of dharma (righteousness)
2. Dharmendra – Indra (king) of dharma
3. Dharmil – One who follows dharma
4. Dharmaraj – King who lives by dharma
5. Dharmin – Righteous, endowed with dharma
6. Deepak – Lamp, light of knowledge
7. Devansh – Part (ansh) of the divine
8. Devendra – King of devas (used in Jain texts also)
9. Divyesh – Lord of what is divine / spiritual
10. Divesh – Lord of wealth / inner richness
11. Dravya – Substance (a Jain philosophical term)
12. Darshan – Vision, spiritual insight
13. Dhaval – Pure, white, spotless
14. Dhiraj – Patience, calmness
15. Dinesh – Lord of the day (sun), often used in Jain families
16. Digant – Horizon, vast expanse
17. Divit – Immortal, blessed life
18. Dhir – Steady, firm, courageous in a calm way

If you’d like, tell me if you prefer very traditional (like “Dharmesh, Dhaval”) or more modern-sounding names (like “Divit, Devansh”), and I can refine the list further.
