‘Or did they go about driving chariots, drawn, by mares with plaited manes and tails, using long wands and goads the while, as you, and your teacher too, do now?’ ‘Not that, Gotama.’ ‘Or did they have themselves guarded in fortified towns, with moats dug out round them and crossbars let down before the gates, by men girt with long swords, as you, and your teacher too, do now?’ ‘Not that, Gotama.’ 10. ‘So then, Ambaṭṭha, neither are you a Rishi, nor your teacher, nor do you live under the conditions under which the Rishis lived. But whatever it may be, Ambaṭṭha, concerning which you are in doubt or perplexity about me, ask me as to that. I will make it clear by explanation.’ 11. Then the Blessed One went, forth from his chamber, and began to walk up and down. And Ambaṭṭha did the same. And as he thus walked up and down, following the Blessed One, he took stock of the thirty-two signs of a great man, whether they appeared on the body of the Blessed One or not. And he perceived them all save only two. With respect to those two — the concealed member and the extent of tongue — he was in doubt and perplexity, not satisfied, not sure.
