The Basics

In Astrology, Mars represents action, energy, and drive. It symbolizes passion, assertiveness, energy, courage, motivation, aggression, willpower, determination, and how we take action.

The Eighth House represents "Transformation and Shared Resources." It signifies transformation, deep emotions, shared finances, inheritances, sexuality, and the occult.

If you have Mars in the 8th House, you possess an intense and passionate nature when it comes to matters of transformation and shared resources. 

You are not afraid to confront deep emotions, explore sexual taboos, or delve into the hidden and mysterious aspects of life.

Your sexual energy is powerful and intense, and you approach intimate relationships with equal passion and desire. You may have a magnetic and charismatic presence that attracts others.

Your investigative nature makes you adept at uncovering hidden information or delving into the mysteries of life. You have a natural curiosity and desire to understand the deeper meaning behind things.

With Mars in the 8th House, you have the energy and drive to transform your life and harness the power of shared resources for your growth and success.

However, it's important to manage any tendencies towards controlling or manipulative behavior. Balancing your intensity with respect for boundaries will foster healthier and more harmonious relationships.

You have the potential to tap into your inner strength and resilience, allowing you to overcome challenges and experience personal transformation on a profound level.

*Look at your Cosmodyne scores to see whether your Mars is Harmonious or Discordant.

While everyone has good and bad days, your Cosmodynes reveal where you lean toward on average.

(As we age, we learn to deal with all of our placements, and hopefully, we evolve into more harmonious beings than our Natal charts suggest.)

Transits to your Mars, especially from the outer planets, can greatly affect its expression as well.
