The key to human resource development is in actualizing individual and collective thinking, feeling and choosing potentials related to our minds, hearts and wills respectively. These capacities and faculties must be balanced and regulated according to the standards of truth, love and justice for individual, community and institutional development, health and well-being. These cognitive, affective and conative faculties are the dynamic focal points for effective interactions with our environments, and are key aspects of learning and development actualized in pursuing the spiritual principles of truth, love and justice. Human nature is conceptualized as consisting of physical, psychological and spiritual qualities. The dynamics among them are considered. The mind, heart and will are associated with the cognitive, emotional and moral intelligences. A brief description of these capacities, faculties, standards and intelligences are given and their importance for human resource development explained. Developing human resources is an intellectual, emotional and moral endeavor. I propose truth, love and justice as the guiding principles for human resource development and actualizing potential.
