[135] How many equanimities about formations (saṅkhārupekkhā) are wholesome? How many are unwholesome? How many are indeterminate? Fifteen¹ equanimities about formations are wholesome; three equanimities about formations are indeterminate; there is no equanimity about formations that is unwholesome.
Wisdom that reflects and stands composed:
eight are the resorts of the mind (citta);
two belong to the worldling,
three are the resorts of the trainee (sekkha),
and three belong to the one devoid of lust,
by which the mind (citta) turns away.
Eight are conditions for concentration (samādhi),
ten are the resorts of knowledge (ñāṇa);
the eighteen equanimities about formations²
are conditions for the three liberations (vimokkha).
These eighteen aspects
are mastered through wisdom:
one skilled in the equanimities about formations
does not tremble amid the various views.
¹ There is also the reading "pannarasa."
² Po. reads "kusalatā saṅkhāresu."
That is knowledge (ñāṇa) in the sense of what is known; it is wisdom in the sense of understanding. Therefore it is said: wisdom as the desire for deliverance, as reflection, and as composure is knowledge of the equanimities about formations.
