We present the our own methodological approach for the development of various practical methods and solutions from the entire range of possible human life issues. This is an approach to understanding and living life in its integrity and diversity, spirituality and materiality, subjectivity and objectivity, as the basis for practical methods in all areas of life. The method is called “LiveDevice” — the human body is considered as a living device that serves as a cognitive tool for distinguishing the levels of life in any of its manifestations.
