In Jain tradition, many mahān shrāvaks did excellent dharma, yet remained गृहस्थ and did not take diksha in that life. A few well-known examples are:

1. Ānand Shravak
2. Kāmdev Shravak
3. Śaṅkh Shravak
4. Chūlāṇī Pitṛ Shravak
5. Sūradev Shravak
6. Sālībhadra
7. Śrēṇik Rājā

These shrāvaks are remembered for:

• strong śraddhā in the Tirthankars,
• deep samyak dharma,
• charity, austerity, and vows,
• but remaining in गृहस्थ life due to karma, family duties, kingly responsibilities, or other life conditions.

If you want, I can also give:

• a bigger list of 20+ shravaks, or
• a short description of each shravak’s dharma and story.
