Jyotish, the science of light is the oldest and the most reliable system of Astrology. Since its origin is from the Vedas, it is also known as Vedic Astrology. According to the Vedas, Karma implies reincarnation or rebirth where thoughts and deeds in a past life affect one's current life situation. Thus, each of us is responsible for the tragedies and good fortunes that we experience in our lives. Our actions in the present will not only affect the immediate future but their repercussions will be felt even in future lifetimes.
