sn.22.128 Saṁyutta Nikāya (Linked Discourses)
Liable To Originate (3rd)
At one time Venerable Sāriputta and Venerable Mahākoṭṭhita were staying near Benares, 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 knowledgeable person defined?”
“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 knowledgeable person is defined.”
