Udanavarga 3.58-59

3.58

「不誦為言垢，不勤為家垢，
不嚴為色垢，放逸為事垢。
慳為惠施垢，不善為行垢，
今世亦後世，惡法為常垢。

"Non-recitation is the impurity of words;
Lack of diligence is the impurity of a household;
Lack of grooming is the impurity of appearance;
Negligence is the impurity of affairs.

Stinginess is the impurity of giving;
Unwholesomeness is the impurity of conduct;
In this world as well as the world to come,
Evil dharmas are constant impurities."

“Absence of (daily) prayer is the disease of (daily) conversation (words). Want of diligence is the disease of a household. Want of becoming dignity is the disease of manner (outward appearance). Carelessness is the disease of business. Stinginess is the disease of charity. Vice is the disease of daily conduct. Both now and hereafter an evil Rule of Life (Law) is an everlasting disease (taint). But the disease of all diseases, than which none is worse, is ignorance. He who is wise (enlightened) should free himself from this. Then, O Bhikshus! there is no disease.”

3.59

「垢中之垢，莫甚於癡，學當捨此，
比丘無垢。」

"Among all impurities,
None is worse than ignorance.
A student should abandon this,
Then a bhikṣu will be without impurity."
