In Chapter 2, “Expedients,” the Buddha taught that his purpose in this world is to cause all people to open the treasury of the wisdom of the Buddha and for them to be shown, attain, and enter into this treasury. The Buddha Wisdom, of course, is the Buddha’s enlightenment; so this is the same as causing people to attain enlightenment. The teachings which have been developed since Chapter 2 are expressed [in Chapter 16, The Duration of the Life of the Tathāgata,] in terms of Sakyamuni’s deepest and most heartfelt desire. [The Duration of the Life of the Tathāgata] chapter’s final words show the Buddha’s hope that all living beings will attain the same Buddhahood which he himself enjoys.
