It is possible that many of you know about the Gateway Voyage. It is a system created by the Monroe Institute several decades ago in which, through the combination of binaural sounds of different frequency (you hear different frequencies in each ear) you can enter different states of relaxation and meditation more easily.
For many years I have had the more than 40 exercises and levels that are included in this odyssey of personal and spiritual development, and as levels advance, more and more you are entering explorations of all kinds of mental states, dimensions, astral travels, etc.
After almost two years since the last time I decided to use them, I have returned to the desire to do the whole tour, and additionally to explain those results I find in each of the sessions. So, starting probably today, I will be making summaries of all those experiences and gladly share them with you.
