MySaju brings one of East Asia's most ancient divination systems to English speakers for the first time. Korean Saju (四柱, Four Pillars of Destiny) has been used for over 1,000 years to map a person's life energy. Unlike Western astrology that focuses only on your sun sign, Saju creates a full chart from your birth year, month, day, and hour — revealing your core energy type, life patterns, and fortune cycles.
