1. In order to perfect personality，one has to "realize" awakening oneself，awakening deeds -- to become a Buddha. In order to become a Buddha, one has to learn the dharma "practiced" by the Buddha -- to learn from the Buddha. In order to learn from the Buddha, one has to "understand" the technique expounded by the Buddha -- Buddhology. In order to understand Buddhology，one has to "put faith in" and accept the "faith, understanding，practice，and realization" of Buddha dharma, one has to follow a virtuous man，listen to right dharma, reflect on oneself rightly，practice dharma and love dharma, realize dharma and attain nirvana.
The "Buddha dharma" of Agama Sutras provide the blueprint of establishing "earthly pure land" and the fundamental ways of managing a peaceful and happy "modern society"："to understand the Buddha dharma"，"to be mindful of the merits of Buddha dharma"，"to have faith in and accept Buddha dharma"，"to follow and practice Buddha dharma"，and "to fulfill Buddha dharma".

Although sentient beings live in "five turbidities"，they can be purified according to the principle of dependent arising and dependent extinguishing.
