釋禪波羅蜜次第法門 10.47

10.47

「若好若醜」者，觀外諸色，善業果報故名好，惡業報故名醜。復次，行者從師所受觀法，觀外緣種種不淨，是名醜色。行者或時憶念，妄生淨想，觀淨色，是好色。復次，行者自身中繫心一處，觀欲界中色有二種：一者、能生婬欲；二者、能生瞋恚。能生婬欲是淨色，名為好；能生瞋恚者是不淨色，故名醜。

'Whether pleasant or ugly': contemplating external forms, those resulting from the retribution of wholesome karma are called pleasant, and those from unwholesome karma retribution are called ugly. Furthermore, when the practitioner, following the contemplation method received from their master, contemplates external conditions as various impurities, these are called ugly forms. If the practitioner at times remembers and falsely generates notions of purity, contemplating pure forms, these are pleasant forms. Furthermore, the practitioner binds the mind to one place within their own body and contemplates that forms in the desire realm are of two kinds: first, those able to give rise to sexual desire; second, those able to give rise to anger. Those able to give rise to sexual desire are pure forms, named pleasant; those able to give rise to anger are impure forms, hence named ugly.
