If Capricorn is on your ascendant, it significantly shapes your personality, and Saturn's influence becomes prominent in your life. However, it's crucial to note that this influence need not be inherently negative. An example is someone I know with Capricorn rising and Saturn in Cancer. This person have qualities of responsibility, maturity, and compassion. He have exceptional endurance and heightened awareness of his surroundings, with high sensitivity to the astral.
When Saturn resides in the first house or is in conjunction with the ascendant, its impact is robust. It might incline a person toward a heightened seriousness, perceiving life as a serious business. This influence can be interpreted or perceived as stoic or even distant and cold at times. However, it's imperative to consider the entirety of the astrological chart for a comprehensive understanding, as the influence of other planetary alignments influence the role in shaping one's personality and tendencies.
