分別功德論 4.37

4.37

所以稱盧醯寗比丘恒坐草蓐第一者，此比丘常坐草蓐除去愛心。云何除愛？雖復金床玉机，都無愛著。或復說曰：若有人施妙座者，亦如施草座無異。愛心既盡，諸結亦盡，便手執草向草作禮。有人問曰：「何以向草作禮？」答曰：「我因此草榮飾心盡。得道由之，即是我師，故向作禮耳。」五百獼猴得生天上，亦以天文陀羅花散於故屍。由屍生天，故來散華。夫貴者必以賤為本，以是因緣，稱坐草蓐為第一。

The reason why Bhikṣu Rohiṇī was praised as foremost in always sitting on a mat of grass is that this bhikṣu constantly sat on a mat of grass to eliminate the mind of craving. How did he eliminate craving? Even if there were golden beds and jade tables, he had no craving or attachment to them at all. Or it is said: if someone offered an exquisite seat, it was no different to him than offering a grass seat. Craving having been exhausted, all fetters were also exhausted; he then took grass in hand and made obeisance toward the grass. Someone asked: 'Why do you make obeisance toward the grass?' He replied: 'Because of this grass, my mind for glory and ornament has been exhausted. Attaining the Path came from this; it is my teacher, and therefore I make obeisance toward it.' The five hundred macaques that attained birth in heaven also scattered heavenly māndārava flowers upon their former corpses. Because they were born in heaven by virtue of those corpses, they came to scatter flowers. Indeed, the noble must take the base as its root; due to these causes and conditions, he was praised as foremost in sitting on a mat of grass.
