無量壽經優婆提舍願生偈註 1.63

1.63

此二句名莊嚴心業功德成就。佛本何故興此莊嚴？見有如來說法云：此黑此白、此不黑不白、下法中法上法上上法，有如是等無量差別品似有分別。是故願言：使我成佛，如地荷負無輕重之殊，如水潤長無莦（惡草）葀（瑞草，括音）之異，如火成熟無芳臭之別，如風起發無眠悟之差，如空苞受無開塞之念。得之于內、物安於外，虛往實歸於是于息。是故言同地水火風虛空無分別。

These two lines are called the accomplishment of the adornment of merits of mental karma. Why did the Buddha originally raise this adornment? He saw that there are Tathāgatas who, in expounding the Dharma, say: "This is black, this is white, this is neither black nor white; inferior dharmas, middling dharmas, superior dharmas, and supreme dharmas." Having such immeasurable distinctions seems to involve discrimination. Therefore he made the vow: "May it be that when I attain Buddhahood, I am like the earth bearing burdens without difference of light and heavy; like water moistening and nourishing without distinction of noxious weeds and auspicious plants; like fire maturing without differentiation of fragrant and foul; like wind stirring and rising without discrepancy of sleeping and waking; like space containing and receiving without thought of opening or obstructing. Obtained within, things are at peace without; coming in vain and returning in fullness are thereby brought to rest." Therefore it is said: "Like earth, water, fire, wind, and space, without discrimination."
