瑜伽論記 4.87

4.87

由欲恚害出離，即說乃至樂根出離者，初欲出離即不淨觀；次恚出離即是慈觀；後害出離即是悲觀。此三出離即是憂苦喜樂四根出離，以慈悲通在四靜慮得。第四靜慮中慈悲即是四受出離，由色出離即是說第四靜慮捨根出離者，此得空處定，離色欲故，即是等四定捨根出離。

On "Escape from desire, ill will, and harmfulness means, up to, the escape from the faculty of pleasure": the escape from desire first refers to the contemplation of impurity; next, the escape from ill will refers to the contemplation of benevolence; last, the escape from harmfulness refers to the contemplation of compassion. These three escapes are precisely the escapes from the four faculties of sorrow, suffering, joy, and pleasure, because benevolence and compassion can be attained throughout the four dhyānas. In the fourth dhyāna, benevolence and compassion are precisely the escape from the four sensations. On "Escape from form means the escape from the faculty of equanimity of the fourth dhyāna": this is because by attaining the concentration of the base of infinite space, desire for form is abandoned, which is the escape from the faculty of equanimity of the four dhyānas and so forth.
