Yoga and Ayurveda (an ancient Indian life science) can be thought of as a practical application of sophisticated and complete understanding of the world and being human in it.
This understanding appreciates how basic elements have come to form the physical matter of the world, including arrangements as complex as the human body. These elements have been classified into three qualities known as the doshas: vata, pitta and kapha. We each have a unique combination of these qualities which forms our constitution. These qualities are present in all aspects of our physical experience, including the environment, other people, foods, and leisure and work activities.
Everything around us and everything we do affects the balance of our doshas and this provides a powerful framework for understanding how our bodies and minds form, function and malfunction into conditions of health and illness or wellbeing and suffering; on all levels from physical to spiritual and everything in between.
