 In the Anguttara Nikaya, training in "higher virtue" includes following the Patimokkha, training in "higher mind" (sometimes simply referred to as "concentration") includes entering and dwelling in the four jhanas, and training in "higher wisdom" includes directly perceiving the Four Noble Truths or knowledge of destruction of the taints.In several canonical discourses, a more "gradual" instruction ("anupubbikathā") is provided to receptive lay people (see also, gradual training).This latter instruction culminates in the teaching of the Four Noble Truths which in itself concludes with the Noble Eightfold Path, the constituents of which can be mapped to this threefold training (see below).
