(Tertiary progressions are a type of astrological prediction that involves moving the planets in a person's birth chart forward in time by a specific increment, known as a "day for a year." This is done to show how the positions of the planets will change over time, and to make predictions about future events and experiences. Tertiary progressions are typically used in conjunction with other astrological techniques, such as transits and solar returns, to provide a more complete picture of a person's life and future.)
（Firdaria is a system of astrological prediction that originated in medieval Persia. It involves dividing a person's life into different time periods, each ruled by a different planet, and interpreting the events that are likely to occur during each of these periods. The length of each time period is determined by the cycles of the planets and the movements of the stars. Firdaria is still used by some astrologers today, although it is not as widely known or used as other astrological techniques.）
（Transits are the movements of the planets through the zodiac, and they play an important role in astrology. As the planets move through the zodiac, they make aspects (angles) to the positions of the planets in a person's birth chart, which can indicate changes or events that are likely to occur in that person's life. Astrologers use transits to make predictions about a person's future, and to provide insight into current experiences and challenges. Transits are one of many tools used by astrologers in the practice of astrology.）
