Working with Angels of Wrath

I’ve never tried working with angels before, and really would like to. I bought the Kindle book Angels of Wrath, and really like it. But…The Stillness…the whole thinking 15 minutes before, 15 minutes in the future, etc. I struggle with that. I wonder if just sitting n breathing and feeling my heart beat harder (like when I close my eyes to draw energy) would suffice…? I’m haven’t tried anything yet, and this is why.

Please answer the questions I asked in order to complete your introduction.
