Từ Điển Thuật Ngữ Phật Học Hán Ngữ
The three states of Vedanā, i. e. sensation, are divided into painful, pleasurable, and freedom from both 苦, 樂, 捨. When things are opposed to desire, pain arises; when accordant, there is pleasure and a desire for their continuance; when neither, one is detached or free. 倶舍論 1.
