A Vedic astrologer is considered an important healer in India, like a doctor. In fact, many Indian doctors are trained as astrologers, since Vedic astrology is inextricably connected to Ayurveda, India's medical system.
One of the most important elements a Vedic astrologer brings to medicine is timing. When planets move in the sky and an individual's planetary cycles change, certain life elements governed by the planets also become activated.
For instance, a person born when the rising sign was 15 degrees Virgo feels heaviness, psychological pressure and worry as Saturn moves closer to that exact degree. The stress caused by this will take a toll on a person's physical body, but will compel the person toward greater responsibility, forgiveness and care of self -- which in turn we can extend to others. Saturn brings this energy so we may correct our mistakes and let go of the past.
Any Ayurvedic doctor or beginning astrology student would be able to see an exact conjunction -- such as that noted above -- and offer caution to the patient accordingly. Ayurveda would take steps to counteract the difficult effects of Saturn, which brings cold, dryness, fear, isolation, responsibility, guilt, and slow digestion, among other things. Ayurveda treats illness by going against the indication. For example, since Saturn brings cold and dryness, an Ayurvedic doctor would recommend warm sesame oil massaged into the skin, preferably by a loved one. Also, warm soup served in small quantities would also be an appropriate treatment.
This is how Vedic astrology and culture sees the inextricable link between the outer universe and the inner universe -- our past karma and our current actions. Remarkably, Western medicine is just starting to realize the connection between how one feels and the health of one's physical body. This link has long been recognized in Indian Vedic science.
