Here are some simple Jain-friendly baby names starting with B (for boy or girl), with short meanings:

For Boys (B):

• Bahubali – great strength; name of a very revered Jain śalākā‑puruṣa
• Bhadrabahu – famous Jain Āchārya; “good / auspicious strength”
• Bhavya – noble, spiritually elevated

• Bhadrā – auspicious, fortunate
• Bala / Baala – young, tender; also used in names like Chandanabālā
• Bhanvi – ray of light (from bhānu = sun)

If you tell me:

• boy or girl, and
• if you prefer very traditional (from Jain itihās / scriptures) or more modern-sounding,

I can narrow it to 4–5 best options with slightly deeper Jain meaning.
