At Sāvatthī. Seated to one side, that mendicant said to the Buddha: “Sir, they speak of this thing called ‘knowledge’. What is knowledge? And how is a knowing one defined?” “Mendicant, it’s when a learned noble disciple understands form, its origin, its cessation, and the practice that leads to its cessation. They understand feeling … perception … choices … consciousness, its origin, its cessation, and the practice that leads to its cessation. This is called knowledge. And this is how a knowing one is defined.”
