How is Understanding the Supreme?

The Blessed Buddha once said!
Bhikkhus, just as, among the
trees of Jambudipa the rose-apple tree
is declared to be the chief, similarly among all the states leading to
enlightenment is the understanding ability declared to be the chief,
that is, for the attainment of the supreme enlightenment!
And what, Bhikkhus, are the states leading to enlightenment?
The ability of
Faith,
Bhikkhus, is a state leading to enlightenment.
The ability of
Energy,
Bhikkhus, is a state leading to enlightenment.
The ability of
Awareness,
is a state leading towards enlightenment.
The ability of
Concentration,
is a state leading to enlightenment.
The ability of
Understanding
is a state leading to enlightenment.
Why so? They are conducive for, leads to and produce enlightenment...
Friends just as, the rose-apple tree among the trees of Jambudipa
is declared to be their chief, so too, among all the states leading to
enlightenment, the ability of understanding is declared to be their
chief, that is, for the attainment of irreversible enlightenment...
