維摩經略疏 10.27

10.27

第三、若入此門見淨不喜、見垢不憂，此釋上第二調伏眾生而取佛土。但諸佛為柔伏一切剛弱之人示有垢淨，那得見此淨穢而起高下憂喜之心。心若憂喜不名調伏，無憂無喜是調伏相。譬如良醫為差病故授甘苦二藥，藥雖有異，差病無殊。若見此醫處二種藥為愈病故，不於醫所生憎愛心。佛亦如是，但為調伏眾生，不可見淨垢為疑也。

Third, regarding "if one enters this gate, one does not rejoice upon seeing purity, nor does one grieve upon seeing defilement": this interprets the second point above, on subduing sentient beings to grasp a buddha-land. The buddhas, solely to gently subdue all hard and weak people, show defilement and purity; how could one see this purity and defilement and give rise to thoughts of high and low, grief and joy? If the mind has grief and joy, it is not called subdued; freedom from grief and joy is the sign of being subdued. For example, a skilled physician, in order to cure illness, administers sweet and bitter medicines; although the medicines differ, the curing of illness is no different. If one sees this physician prescribing two kinds of medicines to heal illness, one does not give rise to hatred or affection toward the physician. The Buddha is also like this: solely to subdue sentient beings, one must not look upon purity and defilement and harbor doubts.
