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

“Mendicants, there are these three eyes. What three? The eye of the flesh, the eye of clairvoyance, and the eye of wisdom. These are the three eyes.”

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

“The eye of flesh, the clairvoyant eye, 
the supreme eye of wisdom: 
these three eyes 
were taught by the supreme person. 

The arising of the eye of flesh 
is the path to the clairvoyant eye. 
When knowledge arises—
the supreme eye of wisdom—
one who gains that eye 
is released from all suffering.”

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