Here are some simple, respectful Jain Sādhvījī-style names starting with the letter “K”. These are suitable for girls and are commonly used in Jain families (especially as religious / spiritual names):

1. Kamalā – lotus; purity and softness of heart
2. Kamalinī – full of lotuses; very gentle and pure
3. Kalyāṇī – auspicious, doing good to all beings
4. Kāntā – pleasant, lovable, full of inner beauty
5. Karunā – compassion for all jīvas
6. Karunāśrī – one whose beauty is compassion
7. Kashmīrā / Kaśmīrā – a traditional feminine name, used in Jain households
8. Kirtī / Kīrtī – good fame earned by dharma and śīl (conduct)
9. Kirtiśrī / Kīrtishrī – glory through noble virtues
10. Komalā / Komal – soft, tender, kind-natured
11. Kṛpā / Krupā – mercy, kindness
12. Kṣamā / Kshamā – forgiveness; very important Jain virtue
13. Kṣamāvatī – one who is full of forgiveness
14. Kusum / Kusumā – flower; symbol of fragrance of good conduct
15. Kusumlatā – creeper of flowers; gentle and decorative by virtues

These are not specific to one sect; both Digambar and Śvetāmbara traditions use such virtue‑based Sanskrit names for sādhvīs and for girls inspired by sādhvīs. Spellings may vary (e.g., Krupa/Kṛpā, Kshama/Kṣamā) but the meaning is same.

If you want, you can pick one main name (e.g., Kṣamā, Karunā, or Kalyāṇī) and then a simpler “home name” for daily use.
