I want to know the answer to the following question:
When did Deshin Shekpa travels start?
All the background I'm provided with is that "Rossabi and others describe a similar arrangement made by Kublai Khan and the Sakya Phagpa lama, writing that Kublai would "sit on a lower platform than the Tibetan cleric" when receiving religious instructions from him.". Is that enough to answer the question?
