"This is in terms of," etc., is second: concluding the answer. What is relied upon is the root consciousness, the consciousness of phenomena, and tathatā, because practitioners of the three vehicles each rely on their respective consciousnesses to perfume tathatā and give rise to practice. "Mutually supporting": fundamentally, it is because tathatā perfumes the false mind, causing it to give rise to longing and aversion, and then the false mind perfumes tathatā, causing it to cultivate this practice. Thus, if one relies on the consciousness of phenomena to perfume tathatā, tathatā in turn supports the practice of the consciousness of phenomena; if one relies on the root consciousness to perfume tathatā, tathatā in turn supports the practice of the root consciousness; hence they mutually support each other. However, because conditions of consciousness have the difference of arising inwardly versus developing outwardly, the practices consequently have the distinction of inner illumination versus external seeking; the causes of slowness and speed are derived from this. In "generating the mind upon realization," the text says: "The marks of this bodhisattva generating the mind have three subtle marks of mind. What are the three? The first is the true mind, the second is the expedient mind, and the third is the karmic-consciousness mind." This is explained in detail below.
