The nature of human knowledge and the mechanisms of cognition, the development of memory and education of the mind, concentration and contemplation, anxiety and calmness, the ability to communicate with people and God - this is what the book “The Power of the Mind” by the famous psychologist Ernst Holmes is about. We always attract to ourselves only what corresponds to our thoughts - this is the immutable law of the power of the mind. Ultimately, a person is exactly what he thinks; he is great in his capabilities if he thinks about the great, and insignificant if he thinks about the insignificant.
