We are part of this nature and our natural state is our balance. Ayurveda in its core deals with laws of nature and the natural elements of the universe. It describes how the energies of universe create our nature at the time of conception even before we are born. That original nature is the state of our balance which is called "Swasta" in the sanskrit language. Swasta is the state in which we are established in self. It is when the doshas are balanced, the digestive fire is balanced, the tissues are balanced, elimination and excretion is balanced, senses, mind and soul are balance. Therefore swasta is health.
