Discernment (
realisation) & consciousness, friend: Are these qualities conjoined or disjoined? Is it possible, having separated them one from the other, to delineate the difference between them?
Discernment & consciousness are conjoined, friend, not disjoined. It's not possible, having separated them one from the other, to delineate the difference between them. For what one discerns, that one cognizes. What one cognizes, that one discerns. Therefore these qualities are conjoined, not disjoined, and it is not possible, having separated them one from another, to delineate the difference between them.
Discernment & consciousness, friend: What is the difference between these qualities that are conjoined, not disjoined?
Discernment & consciousness, friend: Of these qualities that are conjoined, not disjoined, discernment (realisation) is to be developed, consciousness is to be fully comprehended.
