二罪
Từ Điển Thuật Ngữ Phật Học Hán Ngữ
The two classes of offence: (a) 性罪 crime which is wrong in itself, e.g. murder, etc.; (b) 遮罪 crime not wrong in itself, e.g. taking alcohol, but forbidden by the Buddha for the sake of the other commandments; transgression of this is therefore a sin against the Buddha.
