In Vedic astrology, "dashas" refer to planetary periods that influence a person's life experiences and events. Each dasha is associated with a specific planet, and its duration varies. The most commonly used system is the Vimshottari Dasha, which divides a person's life into segments ruled by different planets, allowing astrologers to predict trends and changes. Dashas help in understanding the timing of significant life events, such as career changes, relationships, and health issues. By analyzing the current dasha and its sub-periods, astrologers can provide insights into an individual's strengths, challenges, and opportunities during that time.
