What does
Perfectly Self-Enlightened Mean?

The Blessed
Buddha once said this:
Those who do not understand
Suffering
Who do not know how Suffering comes into being,
Nor where Suffering ceases without remaining trace!
Who do not know this Noble Way & unique Method,
Which leads straight to stilling of all Suffering!
They are indeed incapable of any mental release;
They are neither released through understanding;
Thus
incapable of making an end, stranded, helpless,
They tumble on in birth,
ageing and eternal decay...
But those who do understand this
Suffering,
Who also know
Craving as
The Cause of Suffering,
And where
Suffering ceases completely,
Who
do indeed understand the method of
This Noble Way
Which
surely leads straight to
The End of all Suffering!
They are endowed both with mental
release (ceto-vimutti)
And also release
through understanding
(Pañña-vimutti)
Being thus ready and able of making an
irreversible end,
They stop tumbling on in birth, ageing
and decay...

It is because he all alone has fully
awakened to these
4 Noble Truths
as
they really and actually are, that the
Tathagata is called a worthy
Arahat,
is called a Perfectly Self-Enlightened One, is called a
SammāSamBuddha...
Therefore, Bhikkhus, an effort
should be dedicated to really understand:
All this
is Suffering!
An effort should be made much
of to
truly comprehend:
Craving is the Cause of Suffering!
An
effort should be cultivated to
realize:
No Craving is the End of Suffering! Effort
should be made to break through,
reinforce, and develop:
This Noble 8-fold Way which Ceases all Suffering...
Comments:
Only a
SammāSamBuddha can rediscover
and teach these Four Noble Truths!
