How to see angels and talk to them?

This book is aimed at teaching you without literary detour the protocol that will allow you to see angels as well as to talk to them, most of the time in the parallel worlds in dream state, or exceptionally in the physical world in an awakened state. I am not talking neither about unsure intuitions nor about fuzzy premonition and even less about vague signs that are subjects to interpretations. I am talking about the very concrete way to see angels and to talk with them, occasionally but scarcely to walk in the streets of your city with one of them, and perhaps even with a little chance to end the discussion by shaking their hands. Indeed, that is possible with some degree of religiosity, and by respecting word by word the protocol that I describe in this book.
