大方廣圓覺修多羅了義經略疏 2.359

2.359

謂一切種智由此而得，因果相攝，決定無疑，是以如來印言成就。又此經宗分同《華嚴》，因該果海，果徹因源，稱性互收，無別先後。彼云「若諸菩薩能與如是觀行相應，於諸法中不生二解」，即同此安心之文，「即得阿耨菩提」，同此一切種智。

This means that the knowledge of all modes is obtained from this; cause and effect encompass each other, definitely and without doubt, and therefore the Tathāgata confirms it with the word 'accomplished.' Moreover, the principal tenet of this sūtra is identical to the Huayan: cause encompasses the ocean of fruition, and fruition penetrates the source of cause; conforming to the nature, they mutually embrace, without distinct priority. That [sūtra] says: 'If bodhisattvas can correspond with such contemplative practice and do not give rise to dualistic understanding regarding dharmas,' which is identical to the text here on settling the mind, 'they immediately attain anuttara-bodhi,' which is identical to the knowledge of all modes here.
