The Buddha sometimes described the practice (patipatti) of his teaching as the gradual training (Pali: anupubbasikkhā) because the eightfold path involves a process of mind-body transformation that unfolds over a sometimes lengthy period. The emphasis on gradual training may be understood by the fact that just as the human habits which give rise to suffering have been built up over a long period of time those same habits similarly take a long time to undo requiring a sustained effort achievable only with a genuine commitment to training.
