Jang Tana
Jang Tana, or Tana Monastery, stood in Nangchen in eastern Tibet as a centre of the Yelpa Kagyu tradition. Yelpa Yeshe Tsek took possession of the monastery in 1188, under the patronage associated with the chief of Ling. This older foundation linked the institution with a religious lineage and an aristocratic network that remained important in the later medieval history of Kham.
Tana became particularly associated with relics attributed to Gesar of Ling, including scriptures, weapons and armour. The account of their donation belongs to the monastery's historical tradition; the exact date is uncertain, and scholarship allows that it may have occurred later than the founder's lifetime, perhaps in the fourteenth or fifteenth century. These objects connected Buddhist patronage with the prestige of a regional epic hero. In the wider Nangchen and Kham world, Gesar's oral traditions and Buddhist ritual developed together, especially from the seventeenth century. Tana's setting therefore combines monastic transmission with the preservation and religious interpretation of a shared regional memory.
