Yug is a term that originates from ancient Indian texts, particularly in Hindu cosmology. It refers to an era or age in a cycle of time, with each cycle consisting of four distinct ages: Satya Yuga, Treta Yuga, Dvapara Yuga, and Kali Yuga. Each age has its own characteristics, moral values, and duration, with Satya Yuga being the age of truth and righteousness, while Kali Yuga is often associated with strife and moral decline. In Hindu philosophy, the concept of Yug emphasizes the cyclical nature of time and existence. Each cycle is believed to repeat indefinitely, reflecting the rise and fall of civilizations and the evolution of human consciousness. The current age, Kali Yuga, is said to be marked by challenges, but it also offers opportunities for spiritual growth and transformation.
