Saman Suttam (also called Saman Suttam or Jain Geeta) is a well-known Jain text that is accepted by both Digambar and Shwetambar traditions. It is a compilation of Jain doctrines in Prakrit with English/Gujarati translations in many editions.

Where to look online from the UK:

• Look for reputable publishers of Saman Suttam (often titled Saman Suttam, Samantasuttam, or Jain Geeta) and choose a format you prefer (hard copy, e-book, or PDF). Editions by Sarva Seva Sangh Prakashan are commonly available.
• Check major Jain book portals and libraries that stock Jain scriptures (English, Gujarati, and Prakrit versions are common).
• If you want translations and commentary, some editions include English translations by T.K. Tukol and K.K. Dixit or other scholars.

Notes:

• There are slight textual and interpretive differences between Digambar and Shwetambar editions, especially in transliteration and commentary. The core teachings remain the same, but you may encounter variant spellings or minor explanatory notes depending on the edition.
• Since you’re in the UK, you may also find local Jain centers or libraries that stock Saman Suttam or can order it for you.

If you’d like, tell me which language and format you prefer (English with translation, Gujarati, or Prakrit with commentary), and I can help narrow down a suitable edition available online.
