During this era, the power of mankind was diminished as people became less spiritual and more focused on material possessions. Wars broke out frequently and climate changes became common place, giving rise to deserts and oceans.
Despite these seemingly negative effects, the Treta Yuga also brought knowledge of universal magnetism. This knowledge allowed humans to understand the forces of nature and the true nature of the universe.
Each one of the distinct Yugas is linked to one of the four universal powers of maya and gives mankind the chance to understand this power and bring it under control.
