Essential Dignity & Debility refers to the Strengths and Weaknesses of the Planets Through the Signs.
I always think of the planets as characters and the signs as clothes they can wear. Each time a planet enters a new sign (remember that the planets are always moving) they take on different characteristics.
Take a look at each of these quick reference guides to familiarize yourself with where each planet and sign operates in the BEST and WORST way. It’s even more insightful to see this coming into action as the year moves along and the planets weave in and out of the signs. Also keep in mind that some planets move quickly and others move slowly—so some of us may never really experience certain slower moving planets in certain signs in our life time.
