The Third Discourse on Impossibility
94.
"There are, monks, these six impossibilities.
What are the six?
A person accomplished in right view is incapable of depriving his mother of life, a person accomplished in right view is incapable of depriving his father of life, a person accomplished in right view is incapable of depriving a Worthy One of life, a person accomplished in right view is incapable of drawing blood from a Truth-finder with a malicious mind, a person accomplished in right view is incapable of breaking the monastic community, a person accomplished in right view is incapable of pointing to another teacher.
These, monks, are the six impossibilities."
