MN70 describes the 7 kind of persons, the one liberated by wisdom is described as:
- “What kind of person is one liberated-by-wisdom? Here
some person does not contact with the body and abide in those
liberations that are peaceful and immaterial, transcending
forms, but his taints are destroyed by his seeing with wisdom.
This kind of person is called one liberated-by-wisdom. I
do not say of such a bhikkhu that he still has work to do with
diligence. Why is that? He has done his work with diligence; he
is no more capable of being negligent”.
