Here’s a simple, Jain-focused comparison of the three names:

• Arham

- Meaning (arth): Generally taken to mean “worthy” or “deserving.” In Jain context, it resonates with the idea of spiritual worthiness and progress on the path. - Jain tradition note: The word resembles “Arhat”/“Arham” usage in Indian spiritual vocabulary; it sounds like a virtuous, contemplative name that fits Jain values. - Traditions: No significant Digambar/Shwetambar differences for this name.

• Dhyan

- Meaning (arth): Means “meditation” or focused contemplation. - Jain tradition note: Meditation is a core practice in Jainism (yoga, reflecting on vows, right faith, etc.), so this name aligns well with Jain spiritual discipline. - Traditions: No notable Digambar/Shwetambar split for this name.

• Nimish

- Meaning (arth): Means “moment” or a very short span of time. - Jain tradition note: The concept of mindful, present action can connect to Jain emphasis on right conduct in each moment, though the direct meaning is more general than a specific Jain practice. - Traditions: No significant Digambar/Shwetambar differences for this name.

Recommendation

• If you want a name that clearly reflects spiritual worth and aligns with Jain virtues, consider Arham as the first choice.
• If you prefer a name that foregrounds meditation and inner discipline, Dhyan is a strong second option.
• Nimish offers a unique, time-conscious meaning and a modern feel, good as a distinctive third option.

All three names are suitable in Jain contexts and don’t carry specific sectarian differences.
