Pandit / Brahmachari Sumat Prakash ji was a modern Jain lay-scholar and preacher (mainly associated with Digambar tradition). He is known especially for:

• Simple, practical explanations of Jain siddhānt (doctrine)
• Lectures and books aimed at general Jain families and youth
• Inspiring many people toward samyak darshan, samyak jñān and samyak chāritra through easy language

About his books

He has written / compiled several books and booklets, generally on topics like:

• Basic introduction to Jain principles (jīv–ajīv, karm, bandha–mukti, vrata, etc.)
• Practical Jain life for gṛhasth (householders)
• Paurāṇik kathā (Jain stories) to explain right conduct and non‑violence
• Character-building and moral teachings for children and youth

However:

• I do not have a fully reliable, complete list of all his book names, editions, and publishers.
• Different Jain libraries list slightly different sets of titles, so giving a detailed list from memory would risk inaccuracy.

How you can find his books

For an authentic list of Br. / Pt. Sumat Prakash ji’s books, you can:

1. Check major Jain e‑libraries (like Vitrag eLibrary, JainGrantha, etc.) and search by “Sumat Prakash” in the author field.
2. Ask at nearby Digambar Jain libraries, pathshalā, or local Jain book shops; they often stock his popular titles and can tell you what is currently available or in print.
3. Some of his pravachans are available as audio under titles like “Jain Siddhānt Praveshikā”, which are also sometimes printed in book form by different trusts.

Because I must preserve accuracy and purity of Jain dharma, I am intentionally not guessing individual book titles or publishers.
