In Hindu cosmology, the major cycles of time are referred to as Yugas. These Yugas consist of four primary epochs: Satyuga, Tretayuga, Dvaparayuga, and Kaliyuga, each representing a period defined by the moral and spiritual state of humanity. Satyuga is characterized by truth and virtue, while Kaliyuga, the current age, is marked by conflict and moral decline. These cycles reflect the cosmic order and the cyclical nature of existence, influencing how adherents view time, spirituality, and the progression of life. Each Yuga ends with a renewal, suggesting the possibility of redemption and rebirth.
