But whatever have one root in common with the name-root, are all those phenomena name?
Form (rūpa) originated by name has one root in common with the name-root but is not name; name both has one root in common with the name-root and is name.
Whatever phenomena have one root in common with the name-root, are all those mutual roots with the name-root?
Those name-roots that arise together both have one root in common and are mutual roots; the remaining phenomena arisen together with the name-roots have one root in common with the name-root but are not mutual roots.
