[307] "Furthermore, Sandaka, here some teacher is dull and confused (mando momūho). Because of his dullness, because of his confusion, when asked a question on this or that matter, he resorts to verbal evasion (vācāvikkhepa), to endless equivocation (amarāvikkhepa): 'I do not hold that it is thus; I do not hold that it is so; I do not hold that it is otherwise; I do not hold that it is not; I do not hold that it is not not.' Therein, Sandaka, a wise person reflects thus: 'This worthy teacher is dull and confused. Because of his dullness, because of his confusion, when asked a question on this or that matter, he resorts to verbal evasion, to endless equivocation: "I do not hold that it is thus; I do not hold that it is so; I do not hold that it is otherwise; I do not hold that it is not; I do not hold that it is not not."' Having understood, 'This spiritual life (brahmacariya) is without consolation (anassāsika),' he becomes disenchanted and departs from that spiritual life. This, Sandaka, is the fourth spiritual life without consolation, declared by the Blessed One who knows and sees, the Arahant, the Perfectly Self-Enlightened One, wherein a wise person would, so far as he is able, not live the spiritual life, and if he lived it, would not accomplish the true way (ñāya), the wholesome Dhamma. These, Sandaka, are the four spiritual lives without consolation, declared by the Blessed One who knows and sees, the Arahant, the Perfectly Self-Enlightened One, wherein a wise person would, so far as he is able, not live the spiritual life, and if he lived it, would not accomplish the true way, the wholesome Dhamma."
