The Complete Astrology Cheatsheet: Essential Guide to Cosmic Wisdom

Introduction: What is Astrology and Why It Matters

Astrology is an ancient practice that studies the relationships between celestial bodies and events on Earth, particularly human behavior and personality traits. Dating back thousands of years, astrology has influenced cultures worldwide and continues to be a popular tool for self-reflection, understanding relationships, and navigating life’s challenges. While not scientifically validated, many find value in astrology’s symbolic language and archetypal framework for personal growth and meaning-making.
