Saturn Return - Saturn is symbolically/astrologically associated with time, challenge, fear, doubt, confusion, difficulty, seriousness, heaviness, unwanted burdens and hard lessons, among other more positive things such as structure, significance, accomplishment, reflection, power, prestige, maturity, responsibility and order – this is why astrologers believe that the thirtieth birthday is such a major rite of passage and is considered by many astrologers to mark the 'true beginning' of adulthood, self-evaluation, independence, responsibility, ambition, and full maturation.
