Before they knew it evening had come, and the banquet broke up.
不覺, without noticing, is the standard way this novel ends a good day — the same phrase it used for the prince's fright coming over him unawares. Time slips past when nobody is being chased.
He gave further orders to make up beds and hangings in the Gauze-Airing Pavilion at once, and invited the masters to rest for the night.
床幃 is the bed together with its curtains — a proper bed, hung, rather than a mat on the floor. The pilgrims are being lodged where they ate, which by now has stopped being a slight and become a household arrangement. 安宿 is to pass the night in peace.
The plan was to burn incense early next morning with all sincerity, and bow again to ask that the martial arts be transmitted.
竭誠 is to exhaust one's sincerity, to hold nothing back. The prince has already been told yes, and he is arranging a formal ceremony anyway, because in his world an agreement is not a thing until it has been performed. 傳 is the specific verb for handing on a teaching from master to pupil.
The day ends in the most domestic way possible: beds are made, and everyone plans to get up early.
The detail worth keeping is that the ceremony is being scheduled after the agreement rather than before it. The prince has his answer and still wants the incense and the bowing, and the novel treats that as entirely sensible.
