Sun-South Node: This connection indicates a past life connection in which an imbalance related to authority issues between the two people. In a previous lifetime, perhaps it was a father-child relationship. At any rate, the South Node person did a lot to help the Sun person in a past life, and has now returned for “repayment.” The Sun person feels obligated to pay the South Node person back due to the instant familiarity and comfort. The Sun person gives the South Node person support and help. The South Node person may (inadvertently) drain the vitality of the Sun person, and may, in some way, prevent the Sun person from realizing their full potential.
My first boyfriend’s Sun was conjunct my South Node in Scorpio. We met in the most random, bizarre way, but the chemistry and familiarity was instant. I certainly felt “held back” by the relationship over time; with my North Node in Taurus, my life’s path involves, among many things, working towards valuing myself and fostering my sense of self-respect. With him, I was stuck in a “rut” of sexual exploitation, obsession, and jealousy. After 2 years, I was exhausted, and had no choice but to separate myself from him. True to Scorpionic fashion, we took a long time to fully break up, but I certainly felt a weight had lifted once it was over.
