1 Sãla-sikkhà – training in morality
It comprises three maggaïgas (constituents of the Path):
i Sammà-vàcà – right speech
ii Sammà-kammanta – right action
iii Sammà-àjãva – right livelihood.
2 Samàdhi-sikkhà – training in concentration
This also comprises three maggaïgas:
i Sammà-vàyàma – right effort
ii Sammà-sati – right mindfulness
iii Sammà-samàdhi – right concentration
3 Pa¤¤à-sikkhà – training in wisdom
This training consists of two maggaïgas:
i Sammà-diññhi – right view
ii Sammà-saïkappa – right thought
Though the right view (wisdom) should guide the way
throughout the course of purification, one should begin with
sãla-sikkhà for the purpose of laying down the foundation of the
Path. Based on sãla-foundation, one shall develop concentration
(samàdhi-sikkhà), and based on concentration, one shall practise
vipassanà to develop wisdom (pa¤¤à).
So in the Path of Purification (Visuddhi Magga), sãlavisuddhi
(purity of morality) comes first, and citta-visuddhi
(purity of the mind which refers to samàdhi-sikkhà) comes next.
The remaining five visuddhis correspond to pa¤¤à-sikkhà
(training in wisdom).
The progress along the Path will be marked by the seven
visuddhis, the last visuddhi being the end of the Path. Each visuddhi
is characterised by certain vipassanà-¤àõas (insight-knowledge).
