Any Buddha is a sublimely Well Gone One
(Sugata):

1: Because of the
Way he has travelled,
was good,
2: Because of having gone to an excellent
Destination,
3: Because of having gone there Completely and Absolutely,
4: Because of explaining the
Way
thereto suitably and precisely!
The
Noble 8
fold Way he went, was purified and blameless, since it was without delay,
obstruction, and leading directly to a sublime safety! The excellent place, that
he has
gone to is the deathless state of Nibbāna, which is supreme, since this happy
mode of
existence cannot be found anywhere else! He has furthermore gone there
completely,
absolutely, and irreversibly without ever going back again to the defilements
eliminated
by each stage of the path. For it is said: He does not again turn around,
return, or slide
back to the defilements abandoned by first the
stream-entry,
then the
once-returner,
then the
never-returner and finally the
Arahat path, thus
is he supremely well gone...
From the time of making his resolution at the feet of
Dīpankara
Buddha many
universal
cycles ago, up until his Enlightenment in year 534 BC, by working
solely for the
welfare
and happiness of the entire world, and through the fulfilment of the
thirty
perfections,
and through following the
Middle Way without
ever deviating towards either
of
the two
extremes, that is:
Neither towards indulgence in sense pleasures, nor in
any self-torture,
neither
towards any form
of eternalism, nor to any form of annihilationism, therefore is he
sublimely well
gone (sugata), having gone rightly and exactly down the exceedingly subtle,
razor-sharp,
and
difficult Noble 8-Fold
Middle Way! Then he enunciates and explains this
unique
Way
rightly and exactly by speaking only about what is relevant, what fits the
present
occasion,
and in a way that suits the ability of the many listeners, so that they
understand...
Therefore also is he a sublimely Well Gone (Sugata) One, because of explaining this
Way
faultlessly, systematically, and accurately.
