又若出家之人能觀苦空無常無我。厭離生死志求出世。是為依內。若乖斯行翻為外俗。在家之人。若能厭捨俗情欣慕高志。專崇三寶修持四德。奉行孝悌仁義禮智。貞和愛敬。能行斯行。翻同為內。若違斯旨還同外道。在俗之人。能隨內教。便寤真理心常會道。漸進勝途至趣菩提。既知如是。欲行此行。唯須自卑。推德與他。如拭塵巾。攬垢向己。持淨與人。故經云。退而得者佛道也。

Furthermore, if one who has left household life can contemplate suffering, emptiness, impermanence, and non-self, abhorring saṃsāra and aspiring to transcend the world, this is to follow the inner. If one goes against this practice, one turns instead into an outer worldly person. As for householders, if they can cast aside worldly sentiments, aspire toward high ideals, single-mindedly revere the Three Jewels, cultivate the four virtues, and practice filial piety, fraternal respect, benevolence, righteousness, propriety, wisdom, chastity, harmony, love, and respect—if they can carry out these practices, they turn instead to be aligned with the inner. If they violate these principles, they are no different from non-Buddhists. If worldly people can follow the inner teaching, they will awaken to true principle, their minds will constantly accord with the Way, and they will gradually advance along the superior path until reaching bodhi. Since this is known, if one wishes to engage in this practice, one must only humble oneself and accord virtue to others—like a dust cloth gathering filth to itself and offering cleanliness to others. Therefore a sūtra says: 'Attaining through yielding is the Buddha Path.'
