4.37

The explanation says: In order to understand this verse, one must first know that in the desire realm mental states are of five kinds: wholesome is only one. Unwholesome is of two kinds: first, associated with unshared ignorance (āveṇikī avidyā), meaning this mental state has only ignorance and no other defilements; second, associated with the other defilements such as greed and hatred. Indeterminate (avyākṛta) is of two kinds: first, defiled indeterminate (nivṛtāvyākṛta); second, non-defiled indeterminate (anivṛtāvyākṛta). Now, the text of this verse explains co-arising with reference to these five classes. As for "Because the desire realm has investigation and examination, in a wholesome mental state there are twenty-two mental factors": in the desire realm there must be investigation (vitarka) and examination (vicāra); therefore, in a wholesome mental state twenty-two co-arise—namely, the ten universal mental dharmas (mahābhūmika), the ten universal wholesome mental dharmas (kuśalamahābhūmika), together with investigation and examination.
