"An untaught worldling, O monks, does not know of any other escape from painful feelings except the enjoyment of sensual happiness. Then in him who enjoys sensual happiness, an underlying tendency to lust for pleasant feelings comes to underlie (his mind).
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. Such a one, O 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."
