Haldi powder, or turmeric powder, is a sacred item used in Hindu poojas and religious rituals. Known for its purifying and auspicious properties, haldi symbolizes purity, prosperity, and spiritual well-being. It is often applied to idols, altars, and devotees during pooja ceremonies to cleanse the environment and remove negative energy. Haldi is also used in preparing prasad (sacred offerings), alongside other ritual ingredients like kumkum and flowers.
