Mental protection is not a new concept, but an ancient practice that is found in all cultures. Lifestyle changes, the emergence of new technologies, the severing of ties with ancient religions and traditions led to the fact that the practices of mental protection were for some time forgotten. Modern society is permeated with fear and negativity: you just have to watch TV, social networks, read a newspaper or listen to the news, as we are overwhelmed with anxiety and anger. This atmosphere plays on our emotions and thoughts, making us more vulnerable to manipulation, energy vampires, the interference of otherworldly entities and other dangers. It's time to pay attention to energy hygiene, borders with information flows and people around us. The book "40 Techniques on Mental Self-Defense" will help you fight back against negativity, close holes in the aura, build a reliable barrier and enlist the support of higher powers. You will take control of your mental state and energy field, and extend your protection to people close to you so that light and well-being reign in your space.
