Welcome to the path of discovery and transformation that will take you through the unknown expanses of your inner world. This world is full of secrets and riddles, but sometimes it’s so nice to solve them. However, without a reliable guide it will not be easy, because you do not know what is hidden behind this or that turn. In order not to make fatal mistakes, for which you will subsequently have to pay with the loss of health and faith in the justice of the world, you need to find someone who has already walked this path and continues to explore its hidden corners. Mikhail Katyshev’s book “Angel and Demon: Awareness versus the Unconscious” is exactly the guide that will make your journey easy and enjoyable. But the most important thing is that this work, based on our own experience and research on hundreds of patients, will save time and save us from many problems. Each page here is the key to unlocking the mysteries of your consciousness, opening the door to unprecedented opportunities for self-knowledge and self-realization.
