Posting this quote for AEN who's having problems posting from
his handphone.
"In whatsoever Dhamma and Discipline, Subhadda, there is not
found the Noble Eightfold Path, neither is there found a true
ascetic of the first, second, third, or fourth degree of
saintliness. But in whatsoever Dhamma and Discipline there
is found the Noble Eightfold Path, there is found a true ascetic of
the first, second, third, and fourth degrees of
saintliness. Now in this Dhamma and Discipline,
Subhadda, is found the Noble Eightfold Path; and in it alone are also found
true ascetics of the first, second, third, and fourth degrees of
saintliness. Devoid of true ascetics are the systems of
other teachers."
~ Buddha, Digha Nikaya 16
Important to note is that the entirety of the Noble Eightfold
Path - and not just one part - must be taught in order for there to
be Enlightenment.
