The Fourth Discourse on the Tree
540.
"Just as, monks, whatever trees of the supaṇṇas there are, the thorny red cotton tree is declared the foremost among them;
so too, monks, whatever qualities conducive to enlightenment there are, the wisdom faculty is declared the foremost among them, that is to say -
for enlightenment.
And what, monks, are the qualities conducive to enlightenment?
The faith faculty, monks, is a quality conducive to enlightenment; it leads to enlightenment. Etc.
the wisdom faculty is a quality conducive to enlightenment; it leads to enlightenment.
Just as, monks, whatever trees of the supaṇṇas there are, the thorny red cotton tree is declared the foremost among them;
so too, monks, whatever qualities conducive to enlightenment there are, the wisdom faculty is declared the foremost among them, that is to say -
for enlightenment."
