Who wishes to meet Conway? Why is Chang surprised at this? (Chapter Six)

The High Lama wishes to meet Conway.

“My dear sir, I congratulate you,” he continued. “And I am happy to think that I am in some measure responsible — it was after my own strong and repeated recommendations that the High Lama made his decision. He wishes to see you immediately.”

Chang is surprised because the request is unprecedented.

“Because it is extraordinary and unprecedented — even I who urged it did not expect it to happen yet. A fortnight ago you had not arrived, and now you are about to be received by HIM! Never before has it occurred so soon!”
