Gross, mg.

The eye in the heart is similar to Yatwer's manifestations in AE and Mengedda vomiting up skulls and weapons.
Note that none of this stuff occurs unless people are present, in the case of Yatwer, she requires a priest and/or ritual.
Normally, the outside leaks passively into the world via the watcher/watched connection.
In the above cases the connection is going the other way.
An eye in the heart is the kind of metaphorical trespass Akka expected to find.
I imagine a soul as old and stained as Aurang's would be impervious to that sort of psycho-magic backwash.
