The Discourse on What is to be Fully Understood
163.
At Sāvatthī.
The Venerable Rādha approached the Blessed One;
having approached, he paid respect to the Blessed One and sat down to one side.
To the Venerable Rādha seated to one side, the Blessed One said this:
"I will teach you, Rādha, the phenomena to be fully understood, full understanding, and the person who has fully understood. Listen to that, pay close attention; I will speak." "Yes, venerable sir," the Venerable Rādha assented to the Blessed One. The Blessed One said this: "And what, Rādha, are the phenomena to be fully understood? Materiality, Rādha, is a phenomenon to be fully understood, feeling is a phenomenon to be fully understood, perception is a phenomenon to be fully understood, activities are a phenomenon to be fully understood, consciousness is a phenomenon to be fully understood. These are called, Rādha, the phenomena to be fully understood. And what, Rādha, is full understanding? That which, Rādha, is the elimination of lust, the elimination of hate, the elimination of delusion - this is called, Rādha, full understanding. And what, Rādha, is the person who has fully understood? 'The Worthy One' should be said. This venerable one of such a name and such a clan - this is called, Rādha, the person who has fully understood." The fourth.
