This was said by the Buddha, the Perfected One: that is what I heard.

“Mendicants, there are these three elements. What three? The elements of form, formlessness, and cessation. These are the three elements.”

The Buddha spoke this matter. On this it is said:

“Comprehending the element of form, 
not stuck in the formless, 
those who are released in cessation, 
they are conquerors of death.

Having directly experienced 
the element free of death, 
free of attachments; 
having realised relinquishment 
of attachments, the undefiled 
fully awakened Buddha teaches 
the sorrowless, stainless state.”

This too is a matter that was spoken by the Blessed One: that is what I heard.
