Confused with Sigils Of Power from Archangels Of Magick

Firstly it states that I don’t need to say: “Michael, please protect me from…” and then afterwards, after the writer said when I was done with gazing at the archangel name’s sigil, I had to confirm to him (the archangel) what it is that I want.

Didn’t the writer say that you don’t need to say a phrase and work with feelings and then suddenly I have to confirm what it is that I want.

Does this hinder my ritual if I don’t need to confirm what it is that I want?
