四分律刪繁補闕行事鈔 1.459

1.459

一前須處所。中國布薩，有說戒堂，至時便赴。此無別所，多在講、食兩堂，理須準承。通皆席地。中國有用繩床，類多以草布地；所以有尼師壇者，皆為舒於草上。此間古者有床。大夫已上，時復施安；降斯已下，亦皆席地。東晉之後，床事始盛。今寺所設，率多床座；亦得雙用。然於本事行時，多有不便；隨處量法。

First, the location required beforehand. In India for upoṣadha, there are upoṣadha halls; when the time arrives, they go to them. Here there is no separate place, and it is mostly held in both lecture halls and dining halls; in principle, one should follow this model. Generally, all sit on the ground. In India, rope beds are used, but generally grass is mostly spread on the ground; the reason for having a niṣīdana is entirely for spreading it upon the grass. In this land, of old there were couches. Those of grand master rank and above occasionally arranged them; below this, all sat on the ground. After the Eastern Jin, the use of couches first flourished. What monasteries set up today are mostly couches and seats; using both is also permissible. However, when carrying out the actual practice, it mostly presents inconveniences; one should adapt the practice according to the place.
