12.249

復有異門，謂無量智名方便者，或取四無量相應智或前五無量智為方便體求後後智殊勝性名願體，此文分明說智希求名願體魔不壞道理名力，力還是智，如實智境名智，此為第三番也。

Furthermore, there is an alternative approach: immeasurable knowledge is called 'means'—either taking the knowledge associated with the four immeasurables or the knowledge of the first five immeasurables as the essence of means; seeking the surpassing nature of subsequent knowledge is called the essence of 'vows'—this text clearly states that the aspiring search of knowledge is the essence of vows; the principle of not being destroyed by Māra is called 'power'—power is also knowledge; knowledge of things as they truly are is called 'knowledge'—this is the third round.
