Ayurveda is a science that describes the interaction between human beings and their surroundings, and at the same time, it is also a science of human longevity and vitality.
The fundamental understanding of Ayurveda is that, when a person is disconnected from nature, from his true self, and from a healthy mindset, he becomes sick and gets stuck in unhealthy habits. In order to get healthy, he has to get back to his roots, both within and around nature.
