Yati ("Jati" in vernaculars) historically was the general term for a Jain monk. In the late medieval period it came to represent a stationary monk, who lived in one place rather than wandering as required for a Jain monk. The term was more common for the Śvētāmbara monastics, but was also used by the Digambaras. The term has also been occasionally for ascetics from other traditions.
Some scholars married and were termed Sansari yati or mahātmās.
Some ruling dynasties in Rajasthan had a close relationship with yatis.Abu'l-Fazl ibn Mubarak mentions that yatis were invited to participate in the discussion on religions.
The stationary yatis often managed institutions and properties. Some of their residences are termed Jatiji in their memory.
With reestablishment of orders of wandering (samvegi) monks since late 19th and early 20th century, the number of yatis have declined significantly.
The heads of the institutions of Śvētāmbara Yatis were often termed Shripujya, similar to Digambara institutions headed by the Bhattarakas. Only a celibate yati could become a Shripujya. They have now been replaced by Acharyas who head orders of wandering monks.
Many Yatis were very influential. One of the greatest Marwari trading firm Tarachand Ghanshyamdas was founded as the result of the blessings of a Jain Yati at Churu. The founder, Chaterbhuj, an Aggarwal Poddar, was a devotee of a Jain Yati. The Yati inspired him to go to Bhatinda. which resulted in establishment of a India-wide trading empire. Tarachand Ghanshyamdas is considered to have spawned numerous Marwari trading houses, established by its clerks.
