Cliff:
You missed the point in that making the mind blank (or calm) is
quite different than making the mind closed. Yes, for Harry to
make his mind blank or empty made Voldemort get nothing of value.
As you point out, if Harry had read a joyful book before bedtime
it could have put pleasant thoughts in his mind to share. A person
who has a closed mind does not get involved with any of this, be
the mind agitated or calm.

Snape said, "Time and space matter in magic, Potter. Eye contact
is often essential to Legilimency." (OoP24 PB531) The first
sentence is true, the next is false IMO.

Also, what is normal psychic perception?
