Micchāvāyāmasutta
“Pañcahi, bhikkhave, dhammehi samannāgatā bhikkhunī yathābhataṁ nikkhittā evaṁ niraye. Katamehi pañcahi? Ananuvicca apariyogāhetvā avaṇṇārahassa vaṇṇaṁ bhāsati, ananuvicca apariyogāhetvā vaṇṇārahassa avaṇṇaṁ bhāsati, micchāvāyāmā ca hoti, micchāsatinī ca, saddhādeyyaṁ vinipāteti. Imehi kho, bhikkhave, pañcahi dhammehi samannāgatā bhikkhunī yathābhataṁ nikkhittā evaṁ niraye.
Wrong Effort
“Mendicants, a nun with five qualities is placed in hell as if delivered there. What five? Without examining or scrutinizing, she praises those deserving of criticism, and criticizes those deserving of praise. She has wrong effort and wrong mindfulness, and wastes gifts given in faith. A nun with these five qualities is placed in hell as if delivered there.
