Vedic astrology, called “Jyotish,” means “the science of light.” Vedic science comes from the Vedas, one of the oldest spiritual scriptures of India. It was revealed to the great sages of India around 1,500-2,000 BCE. The great sage Maharishi Parashara was the most influential; his Brihat Hora Sastra is still the most referenced text, and has many translations. There were eighteen great sages, but the most popular today and the principles outlined in this book are primarily from Parashara.
