起信論疏筆削記 9.43

9.43

住相，四：初、能觀。疏　初地等者，謂十地菩薩皆證真如，依真如法為自體，故名法身菩薩。以十地滿心便成正覺，故此位中但標前九。

The mark of abiding has four [parts]: First, the subject of contemplation. The Commentary explains: "The first bhūmi..." means that the bodhisattvas of the ten bhūmis all realize tathatā and take the dharma of tathatā as their own essence; hence they are called "dharmakāya bodhisattvas." Because at the culminating mind of the tenth bhūmi one immediately achieves perfect enlightenment, in this stage only the first nine are indicated.
