17.81

釋曰：染業不應作者，有說染污三業名不應作，謂從非理作意生故。有說亦壞軌者，有餘師說：非直染業名不應作，壞軌則亦名不應作，壞軌則者是無記業也。應如是行住，應如是著衣食，若不如是，名不應作，違禮儀故。

Explanation: "Defiled karma is not to be done": some say that the three defiled karmas are called 'not to be done', because they are produced from improper attention. "Some say that which violates proper conduct is as well": other masters say that it is not merely defiled karma that is called 'not to be done'; violating proper conduct is also called 'not to be done'. That which violates proper conduct is neutral karma. One should walk and stand like this; one should wear clothing and eat like this; if one is not like this, it is called 'not to be done', because it contradicts etiquette and decorum.
