Ayurveda has its source in ancient Vedic literature. It is a Sanskrit word, derived from two roots: ayur, which means life, and veda, knowledge. Science, according to the ancients, is knowledge arranged systematically and logically, and in the course of time ayurveda became known as the science of life—a science so vast that it encompasses our entire being: body, mind, and spirit.
Ayurveda professes a lifestyle regime which not only includes eating foods which pacify your particular dosha(s), but which includes moving your body through yoga, and pranayama to increase balance, flexibility and life force in mind and body. It encourages discovering and practicing your dharma (life purpose or passion) as a key to your own happiness. It promotes expanding your mind, perspective and behavior through learning, understanding, compassion and tolerance. Ayurveda works with your own energies to help you to optimize your well-being.
There is constant interplay between sattva, rajas, and tamas in every individual consciousness, and the relative predominance of one or the other is responsible for differences in psychological and moral dispositions. Sattvic qualities, for instance, manifest as consciousness, purity, and clarity of perception, which in turn make for goodness and happiness. People in whom sattvic qualities predominate are religious, loving, compassionate, and pure-minded. Following truth and righteousness, they have good manners, behavior, and conduct. They do not get easily upset or angry. Although they work hard mentally, they do not get mental fatigue. They are fresh, alert, aware, and full of luster, wisdom, joy, and happiness.
