俱舍論疏 22.178

22.178

論「有不淨觀至有差別故」，四句分別也。已熟非自在小，未熟是自在小。緣自身是所緣小，緣至海非所緣小。有所緣小非自在小者，謂已熟修緣自身也。有自在小非所緣小，謂未熟修所緣至海。有自在小亦所緣小，謂未熟唯緣自身。有非自在小亦非所緣小，謂已熟修緣至海也。已熟等中，已熟是第一句，未熟是第二句，未熟是第三句，已熟是第四句。所緣中云自身是第一句，至海是第二句，更自身是第三句，更至海是第四句。具足作文應言：自身至海。自身至海，闕一重也。

The treatise says, "There is contemplation of impurity... because of the distinction," which is an analysis into four alternatives. Practiced familiarity is not small in mastery; not yet familiar is small in mastery. Focusing on one's own body is small in object; focusing up to the ocean is not small in object. That which is small in object but not small in mastery refers to practiced familiarity focusing on one's own body. That which is small in mastery but not small in object refers to not yet familiar, with the object extending up to the ocean. That which is small in mastery and also small in object refers to not yet familiar, focusing only on one's own body. That which is not small in mastery and also not small in object refers to practiced familiarity focusing up to the ocean. Among practiced familiarity, etc., practiced familiarity is the first alternative; not yet familiar is the second alternative; not yet familiar is the third alternative; practiced familiarity is the fourth alternative. Among the objects, "one's own body" is the first alternative; "up to the ocean" is the second alternative; "again one's own body" is the third alternative; "again up to the ocean" is the fourth alternative. If the text were fully written out, it should say: "one's own body, up to the ocean; one's own body, up to the ocean"—it lacks one repetition.
