On page 444 of The Manuals of Buddhism (the English translation of the Dipanis by Ledi Sayadaw) it is stated that:
[According to the method of sukkhavipassaka-puggala (one who practices insight only), samatha (calm) and aanaapaana (exhaling and inhaling) etc., are not practiced separately. After observing the three constituents of the morality-group of the Eightfold Path, the practice of the wisdom-group of the Eightfold Path is undertaken. The three constituents of the concentration-group of the Eightfold Path come along together with the two constituents of the wisdom-group of the Eightfold Path, and these two sets are termed pa~nca"ngikamagga (the five constituents of the Eightfold Path). These five form one group and together with the aforesaid three constituents of the morality-group of the Eightfold Path they become the Noble Eightfold Path.]
Han: In Myanmar the pa~nca"ngikamagga (the five constituents of the Eightfold Path) is quite well-known. It is also called the "working" magga"nga. When one is on vipassanaa meditation, before he attains magga ~naa.na, he is developing only these five constituents.
However, this pa~nca"ngikamagga is not known by non-Myanmar Buddhists in other countries. Maybe, it is because they cannot find it in the suttas.
Sir, my question therefore is whether the Buddha mentions this pa~nca"ngikamagga in any of the sutttas?
Thank you very much.
