Lecture Notes on the Sūtra of the Collection of the Father and Son (187)

Buddhist practice is the cultivation of the deluded mind of the seven consciousnesses

To sum up, practice is the cultivation of the deluded mind of the seven consciousnesses. When the deluded mind is well cultivated and the mind becomes tranquil, and there are no seeds of unwholesome karma in the Ālayavijñāna, one becomes a Buddha and can restore one's original countenance. At present, the karmic seeds contained in our Ālayavijñāna are tainted and accompanied by ignorance, and our mind of the seven consciousnesses has the afflictions of greed, hatred, and delusion; whereas the Buddha's mind of the seven consciousnesses is entirely tranquil, has already transformed the consciousnesses into wisdom, and is completely without self.
