Mars rules 1st and 8th house is in 8th house in Scorpio
As a Jyotish astrologer, I can tell you that having Mars in the 8th house in Scorpio sign can have a significant impact on a person's life.
The 8th house represents transformation, hidden secrets, mysticism, and the occult. Mars, on the other hand, is the planet of aggression, passion, and energy. When Mars is placed in the 8th house, it can make a person highly motivated to pursue their goals and desires, but this can also lead to a tendency towards impulsiveness and recklessness.
The sign of Scorpio is associated with secrecy and hidden depths. Therefore, when Mars is in Scorpio, it intensifies the energy of the 8th house, making it powerful and transformative. However, it can also make a person prone to jealousy, possessiveness, and a tendency towards hidden agendas.
Overall, having Mars in the 8th house in Scorpio sign can be both a blessing and a curse. It can lead to a deep understanding of the occult and mysticism, leading to the potential for significant transformation in a person's life. However, it can also bring challenges in relationships and the potential for self-destructive behavior.
