I will add this text to create other connections. A Persian text written in the 15th century by Mir Muhammad ben Khawand still reports this tradition. Jesus would have traveled and been to Nusaybin:
"Jesus (peace be upon him) was called "the Messiah" because he was a great traveler. He wore a wool scarf on his head and a wool coat on his body. »
This refers us to the Sufis (one of the etymological hypotheses comes from the Arabic word wool "sûf"). According to Arab tradition, Muhamad wore a coat during sessions of divine inspiration, which according to the descriptions resemble "shamanic transes" (it became a relic for Muslims). In these details we can find Christian and Jewish influences at most from Muhamad (cf. Elijah's mantle because the mantle, in the Bible, participates in man's power with divine contact).
Moreover, according to Orthodox Muslim accounts, a Nestorian Christian monk recognized the "mark of prophecy" between Muhamad's two shoulder blades when he was between 9 and 12 years old and accompanying his uncle Abu Talib to Bosra in Syria. Then there is Khadija's cousin, Muhamad's first wife: Waraqa ibn Nawfal. He was according to Arab accounts a Nestorian priest. Other studies suggest that he was from the Judeo-Nazarene sect. Waraqa played an important role in Muhamad's "instruction".
Sorry for these digressions, I hope this text will be useful for some of you.
So there seem to be interesting connections between Issa/Jesus and a sacred lama at the tibet and in India, probably a complex mixture between the spread of Eastern Christianity and a real character. There is also this group around the apostle Thomas who moved with his beliefs.
Did you read what I posted? Do you realize that "Jesus" is a mythical creation, a composite designed to hide the fact that the Jewish Messiah was a Zealot rebel against Rome?
