維摩經玄疏 4.56

4.56

第五、約觀心明四教者，從三觀起四教，已如前辨。今但論即心行用，識一切教門皆從初心觀行而起四教。既攝一切經教，若一念觀心分明，能分別一念無明因緣所生之心，四辨歷念，則一切經教大意，皆約觀心通達。就此即為四意：一，約觀心明三藏教相；二，約觀心明通教相；三，約觀心明別教相；四，約觀心明圓教相。

Fifth, regarding clarifying the four teachings in terms of contemplating the mind: that the four teachings arise from the three contemplations has already been discerned above. Now we merely discuss practicing and applying directly upon the mind, understanding that all doors of teaching arise from the contemplation practice of the initial mind. Since they subsume all sūtra teachings, if one's contemplative mind is clear in a single thought, capable of distinguishing the mind produced from conditions of a single thought of ignorance, and traversing each thought through the four analytical knowledges, then the general intent of all sūtra teachings is penetrated in terms of contemplating the mind. Regarding this, there are four points: first, clarifying the characteristics of the Tripiṭaka teaching in terms of contemplating the mind; second, clarifying the characteristics of the shared teaching in terms of contemplating the mind; third, clarifying the characteristics of the distinctive teaching in terms of contemplating the mind; fourth, clarifying the characteristics of the perfect teaching in terms of contemplating the mind.
