Vibhuti (also known as Bhasma in Sanskrit) is a sacred ash that is used in Hindu religious practices. It is made from the burning of sacred herbs, wood, or cow dung in a sacred fire, and then the ash is collected and processed to make Vibhuti.

It is commonly used by Hindus as a symbol of purity and spiritual power, and is applied to the forehead as a sacred mark or tilak during worship or religious ceremonies. It is also believed to have medicinal and healing properties and is used in Ayurvedic medicine for various ailments. Vibhuti is considered a powerful purifying agent and is used in the purification of people and spaces during various Hindu rituals.
