"He does not know, according to facts, the arising and ending of these feelings nor the gratification, the danger, and the escape connected with these feelings. In him who lacks that knowledge, an underlying tendency to ignorance as to neutral feelings comes to underlie his mind. When he experiences a pleasant feeling, a painful feeling, or a neutral feeling, he feels it as one fettered by it, caught up in it. Such a one, oh monks, is called an untaught worldling who is fettered by birth, by old age, by death, by sorrow, lamentation, pain, grief, and despair. He is fettered by suffering, this I declare."
