佛說觀佛三昧海經 6.8

6.8

佛告大眾：「夫慈心者，應當起想先緣所親，繫念之時念己父母受諸苦惱有不孝者；念己妻子、所愛眾生受諸苦惱；有見眾生，癩病㿈瘡。見已作念：『當云何救？』一想成已應作二想；二想成已應作三想；三想成已滿一室想；一室想成已滿於僧坊；一僧坊成已滿一由旬；一由旬成已滿一閻浮提；閻浮提成已滿弗婆提；弗婆提成已滿三天下，如是漸廣滿十方界。

The Buddha said to the great assembly: "Now, as for the benevolent mind, one should form a visualization, taking first one's relatives as the object. When fixing one's mindfulness, one thinks of one's own parents undergoing various suffering and distress, and of those who are unfilial; one thinks of one's own wife, children, and loved sentient beings undergoing various suffering and distress; and seeing sentient beings who have leprosy and ulcerous sores, having seen them, one thinks: 'How shall I save them?' When one visualization is accomplished, one should make a second visualization; when the second visualization is accomplished, one should make a third visualization; when the third visualization is accomplished, one fills one room with the visualization; when the visualization of one room is accomplished, one fills a monastery; when that of one monastery is accomplished, one fills a yojana; when that of one yojana is accomplished, one fills one Jambudvīpa; when that of Jambudvīpa is accomplished, one fills Pūrvavideha; when that of Pūrvavideha is accomplished, one fills the three continents; thus expanding gradually, it fills the realms of the ten directions.
