Vibhuti, also known as sacred ash, is a revered substance in Hinduism. Associated with Lord Shiva, it symbolizes the destruction of ego and attachment. Created from cow dung and wood, vibhuti is used in rituals such as abhishek (ceremonial bath), tilak (mark on the forehead), and is often applied to the body by sadhus (holy men). It is believed to possess purifying, healing, and protective qualities, and is a reminder of the ephemeral nature of life.
