Kalyug is the fourth and final age in the cycle of Yugas in Hindu philosophy. It is characterized by a decline in morality, spirituality, and righteousness. This age is believed to be marked by increased conflict, materialism, and a general loss of values among people. According to Hindu scriptures, Kalyug began after the end of Dvapara Yuga and is said to last for 432,000 years. During this period, it is thought that individuals will face greater challenges in maintaining their ethical and spiritual practices, leading to a world where truth and virtue are often overshadowed by deceit and selfishness.
