The 1st house in astrology represents our physical appearance, personality, and how we present ourselves to the world. It is the starting point of the astrological chart and sets the tone for the rest of the houses. The 1st house reveals our self-image, self-expression, and overall identity. It influences our behavior, attitude, and approach to life. The planets and signs in the 1st house provide insights into our strengths, weaknesses, and personal style.
