We, ignorant icchantika of the Latter Age, always drowned in the sea of life and death, are desirous of believing the Lotus Sūtra. It forecasts our inherent Buddha-nature being revealed. Grand Master Miao-lê explains this in his Annotations on the Great Concentration and Insight, fascicle 4, “Unless the Buddha-nature in each of us develops gradually to fill our minds, how can we attain Buddhahood? It is this wonderful power of the Buddha-nature in each of our minds that enlightens us. Therefore, we call this wonderful power of the Buddha nature our teacher-protector.”
