釋禪波羅蜜次第法門 6.37

6.37

善修者，是慈心牢固。初得慈，不名為善修；非但愛念眾生中，非但好眾生中，非但益一眾生中，非但一方眾生中，名為善修。行者於上親、中親、下親、上中人、中中人、下中人、下怨、中怨、上怨，是九種人中，愛憎正等無異，乃至愛念五道眾生中，以一慈心視之如父如母，如兄弟、子姪、知識，常求好事，欲令利益安樂，如是之心遍滿十方，是名善修。復次，若但與眾生欲界樂，不名善修；但與初禪樂，不名善修；但與二禪樂，不名善修。若能具足與欲界樂，乃至三、四禪樂，是名善修。如是慈心，名眾生緣。或在凡夫人行處，或有學人未漏盡者亦行此悲為調心，得大福德，入無漏故。

Regarding "cultivated well": this means the benevolent mind is firm and solid. When first attaining benevolence, it is not called cultivated well; it is not called cultivated well merely within beloved sentient beings, nor merely within good sentient beings, nor merely within benefiting one sentient being, nor merely within sentient beings of one direction. When the practitioner maintains affection and aversion equally without difference among the nine kinds of persons—superior dear ones, middling dear ones, inferior dear ones, superior neutral persons, middling neutral persons, inferior neutral persons, inferior hostile ones, middling hostile ones, and superior hostile ones—and even extends affectionate regard among sentient beings of the five destinies, viewing them with a single benevolent mind as father and mother, as brothers, children, nephews, and good friends, constantly seeking good things, wishing to bring them benefit, peace, and happiness, and such a mind pervades the ten directions, this is called cultivated well. Furthermore, if one only gives sentient beings the happiness of the desire realm, it is not called cultivated well; if one only gives the happiness of the first dhyāna, it is not called cultivated well; if one only gives the happiness of the second dhyāna, it is not called cultivated well. If one is able to fully give the happiness of the desire realm up to the happiness of the third and fourth dhyānas, this is called cultivated well. Such a benevolent mind is called conditioned upon sentient beings. It may be the sphere of action of ordinary persons, or learners whose defilements are not yet exhausted also practice this compassion to harmonize the mind, obtain great merit, and enter undefiledness.
