1 At one time Venerable Sāriputta and Venerable Mahākoṭṭhita were staying near Varanasi in the deer park at Isipatana. …
Mahākoṭṭhita said to Sāriputta:
“Reverend Sāriputta, they speak of this thing called ‘knowledge’. What is knowledge? And how is a knowing one defined?”
2 “Reverend, it’s when a learned noble disciple truly understands form, which is liable to originate … liable to vanish … liable to originate and vanish, as form which is liable to originate and vanish.
They truly understand feeling … perception … choices … consciousness, which is liable to originate … liable to vanish … liable to originate and vanish, as consciousness which is liable to originate and vanish.
This is called knowledge. And this is how a knowing one is defined.”
