“Whatever nun, being invited or being satisfied, should eat or partake of solid food or soft food, there is an offence of expiation.”
Whatever means: … nun is to be understood in this case.
Being invited means: being invited to any one meal of the five (kinds of) meals.
Being satisfied means: eating is to be seen, a meal is to be seen, standing within a reach of the hand, she asks (her), a refusal is to be seen.
Solid food means: setting aside the five (kinds of) meals, conjey, food (that may be eaten) during a watch of the night, during seven days, during life, the rest means solid food.
Soft food means: the five (kinds of) meals: … meat.
If she accepts, thinking: “I will eat, I will partake of,” there is an offence of wrong-doing. For every mouthful, there is an offence of expiation. If she accepts for the sake of nutriment (food to be eaten) during a watch of the night, during seven days, during life, there is an offence of wrong-doing. For every mouthful, there is an offence of wrong-doing.
There is no offence if, being invited (but) not being satisfied, she drinks conjey; if she eats having asked the owner (for permission); if when there is a reason she makes use of (food to be eaten) during a watch of the night, during seven days, during life; if she is mad, if she is the first wrong-doer.
