Ayurveda provides us with a complete understanding of what is life-sustaining and what is not, not just for the physical body, but also our mind, heart, senses and spirit. This includes descriptions of the kind of diet, lifestyle and behavior that is optimal for well-being, the ideal environment, and the herbal rasayanas that are good or bad for each of these aspects of health. There is great detail on each of these modalities--what to eat, when to eat and how to eat are a part of dietary recommendations, for example. The texts also include recommendations for nurturing relationships and living as part of the human community.
