Management and performance are interdisciplinary, spanning diverse fields such as business, industry, government, sports, arts, health and education. In four studies, world-class performers in a variety of fields, for example, management, sports and classical music, have been found to display higher mind–brain development than matched average-performing control groups, including more frequent peak experiences. In this article, we will use a selection of clearly articulated peak experiences reported by these world-class performers to illustrate the subjective or inner nature of optimal performance. (...) Such performance seems to be characterized by inner calmness and happiness amidst dynamic activity, maximum wakefulness, effortlessness and ease of functioning, and a sense of perfection. In order to provide an adequate theoretical framework for understanding peak experiences, we combine Western developmental psychology with the advanced growth range of higher consciousness, as outlined in the ancient Vedic knowledge of India.
