No.
Ennās are like phone numbers,
all that might happen,
is that he listens to you,
and waits for you to give him a command.
Just because you notice a presence,
that doesnāt mean youāre attacked.
Thereās a mental part with it,
however,
if you strongly belief the Demon is hostile towards you,
heāll consider that your request and fulfill it.
That however, normally doesnāt happen right away,
because the Demons are familiar with initial fear while summoning,
often caused by religious dogma making people belief badly about them.
The best approach you can take,
when working with demons,
is aproaching them on an āi am okay, you are okayā equal grounds level.
Donāt pray to them in submission,
but also donāt boss them around.
Simply be respectful,
as you would be with any normal person.
in regards to the Demon youāve listened the enn to,
simply hearing it,
doesnāt automatically call the Demon.
Even if heās there,
thereās a difference between you chanting (saying) the enn yourself,
and having the intent to connect with the demon,
or just stumbling across it randomly.
Donāt worry youāre not under attack,
from just hearing an Enn.
If you want to connect with him,
the best,
and most simple approach is to formulate (say out loud),
your intent of getting to know him.
That usually works well.
Sincerely,
Ā„āBerioth
