[185] Then the Blessed One, having discerned with his own mind (citta) the reflection in the mind of the brahmin Soṇadaṇḍa, thought: "This brahmin Soṇadaṇḍa is troubled by his own mind. What if I were to ask the brahmin Soṇadaṇḍa a question concerning his own teacher's doctrine of the threefold Vedic knowledge (tevijjaka)?" Then the Blessed One said to the brahmin Soṇadaṇḍa: "Brahmin, endowed with how many factors do the brahmins declare one to be a brahmin, so that, saying 'I am a brahmin,' he would speak rightly and would not fall into false speech?" Then it occurred to the brahmin Soṇadaṇḍa: "What indeed was my wish, my hope, my intention, my longing — namely: 'Oh, may the ascetic Gotama ask me a question concerning my own teacher's doctrine of the threefold Vedic knowledge; surely I could satisfy his mind with my answer to the question' — and here, if the ascetic Gotama asks me a question concerning my own teacher's doctrine of the threefold Vedic knowledge, surely I shall satisfy his mind with my answer to the question."
