疏「隨所得位」者，然論釋云「此菩薩同得位時名為善住。」遠公有二釋：一明同上王子得位時，二同佛得位時。

Regarding the commentary's 'According to the stage attained': now, the treatise explains, 'When this bodhisattva simultaneously attains the stage, it is called well-abiding.' Master Huiyuan has two explanations: first, clarifying that it is simultaneous with the prince attaining the stage above; second, that it is simultaneous with a Buddha attaining the stage.
