Ayurveda (pronounced I-your-vay-da), the science of life, prevention and longevity is the oldest and most holistic or comprehensive medical system available. It was placed in written form over 2,000 years ago in India, it is said to be a world medicine.
Before the advent of writing, the ancient wisdom of healing, prevention and longevity was a part of the spiritual tradition of a universal religion.
Medical knowledge from all areas of the world gathered in India, and the famous sage Vyasa, put into writing the complete knowledge of Ayurveda, along with the more directly spiritual insights of ethics, virtue and Self-realization. What is fascinating is the methods used to acquire this knowledge of the uses of herbs, foods, aromas, gems, colors, yoga, mantras, lifestyle and surgery.
The sage-physician/surgeons of the time were the same sages or seers, deeply devoted holy people, who saw health as an integral part of spiritual life. It is said that they received their training of Ayurveda through direct cognition during meditation. In other words, the knowledge of the use of the various methods of healing, prevention, longevity and surgery came through Divine revelation; there was no guessing or testing and harming animals.
