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.
