22.33

四聖種亦爾者，釋第三因也。能生眾聖故名聖種，四聖種體亦是無貪，同前喜等，故言亦爾。

"The four noble lineages are also like this" explains the third cause. Because they can give birth to noble ones, they are called noble lineages; the substance of the four noble lineages is also non-greed, the same as the contentment and so forth above; therefore it is said to be 'also like this'.
