Thina

Thīna (Sanskrit, Pāli: थीन thīna) is a Buddhist term that is translated as "sloth". Thīna is defined as sluggishness or dullness of mind, characterized by a lack of driving power. In the Theravada tradition, thīna is said to occur in conjunction with middha (torpor), which is defined as a morbid state that is characterized by unwieldiness, lack of energy, and opposition to wholesome activity. The two mental factors in conjunction are expressed as thīna-middha (sloth-torpor).
