又能棄捨下，第九善根清淨。按地經云：佛子譬如本真金，善巧金師作莊嚴具已，繫在閻浮提王若頭若頂，閻浮提人餘寶莊嚴具無能奪者，如是菩薩住不動地，彼諸善根一切聲聞辟支佛乃至七地菩薩所不能壞，菩薩得以地大智光明滅諸眾生煩惱闇障。又言：譬如千世界王大梵天王能於一時流布慈心滿千世界，亦能放光遍照其中，如是菩薩住此地中能放身光照十千萬三千大千世界微塵數世界眾生，漸能滅除諸煩惱火令得清涼。

From "Furthermore, able to abandon..." downward, the ninth [section explains] the purity of roots of goodness. According to the Daśabhūmika Sūtra: "O Son of the Buddha, just as original genuine gold, fashioned into an ornament by a skilled goldsmith and bound onto the head or crown of the king of Jambudvīpa, cannot be surpassed by any other jewel-ornament of the people of Jambudvīpa; in this way, when the bodhisattva dwells in the Immovable Stage (Acalā-bhūmi), all his roots of goodness cannot be destroyed by any śrāvaka, pratyekabuddha, or even a bodhisattva of the seventh stage. The bodhisattva is able, by means of the great wisdom-light of this stage, to extinguish the dark hindrances of the afflictions of sentient beings." It also says: "Just as the Great Brahmā King, ruler of a thousand worlds, can at one time spread his mind of loving-kindness to fill the thousand worlds and also emit light to illuminate them everywhere; in this way, the bodhisattva dwelling in this stage can emit bodily light illuminating sentient beings in worlds as numerous as the dust motes of ten times one hundred thousand trichiliocosms, and can gradually extinguish the fires of all afflictions, causing them to attain coolness."
