“Yog Tilak Suri Marasaheb” looks like the name / title of a Jain sadhu, with:

• “Suri” – an honorific usually used for senior Āchāryas or highly learned Jain monks (more common in Śvetāmbara tradition).
• “Mara Saheb / Maharaj Saheb” – a respectful way of addressing a Jain monk.
• “Yog Tilak” – likely an honorific title given by his sangh or guru‑paramparā, but I do not have authentic, detailed information on this specific Suri Maharaj in my data.

I don’t want to guess about his life, lineage, or works without a reliable Jain source. For accurate details, it is best to:

• Ask in your local Jain sangh / upāśray where his pravachan or photos are known, or
• Check printed Jain directories (saṃgh‑nirdeshikā / sādhu‑saṃgh lists) of your own gaccha or sampradāy.

If you tell me what exactly you want (e.g., meaning of his title, general role of a Suri in Jainism, or something else), I can explain that part in simple Jain terms based on śāstra and tradition.
