Here are Jain-friendly boys’ names starting with K, with brief meanings that reflect virtuous qualities often valued in Jain dharma:

• Kalayanjan (auspicious, virtuous)
• Kalyan (auspicious, benevolent)
• Kalyanendra (king of auspiciousness)
• Kalyanak (auspicious event)
• Kumud (lotus; symbol of purity)
• Kumaran (prince; youthful energy)
• Keshav (one who protects; a respectful name often used for spiritual seekers)
• Keshan (bright, radiant)
• Kshiraj (moon-like brightness; serene)
• Kanak (golden; precious)
• Kanaiya (beloved; gentle)
• Kavya (poetry; cultured)
• Kaviraj (poet-king; refined)
• Kavi (poet; wise speaker)
• Karun (compassion, mercy)
• Karunya (mercy; compassion)
• Kshama (forgiveness; tolerant)
• Kshiranjan (moonlike calm)
• Kshitij (horizon; expansive vision)
• Kriti (creation; accomplishment)

Notes:

• These names are common in Indian contexts and can suit a Jain family, especially when chosen for their virtuous meanings.
• If you’d like, I can tailor a list to specific traditions (Digambar vs. Shwetambar) or suggest combinations that pair well with a family surname.

Would you like me to generate more options or pick names that specifically emphasize virtues like ahimsa (non-violence), aparigraha (non-attachment), or samyak darshan?
