The ash-Vibhuti has several symbolic meanings: When eaten, Vibuthi imparts the blessings (Sanskrit: adhishthana) of the divine. Placed on the forehead of devotees, it serves as a sectarian mark (tilaka). In worship connected with Lord Shiva it is a symbol of purity and is one of the main sacraments given at pūjā in all Śaivite temples and shrine. It serves as a reminder to the believer to cast away selfish and worldly desires that wrap the self in Maya, and calls to mind the story of how Shiva burned Kama (the god of desire) to ashes when Kama attempted to break Shiva’s focus on the Divine Truth. The most common reason produced by Hindus for this practice is one should always remember that nothing in this world is permanent and even his own (self – who applies it) body would one day end up in a cup of ash. So every human should abolish his selfishness and develop love among every creature in this world. Vibhuti created from sacred fire (Homa) also contains positive energy. This energy prevents our body from the attack of negative energy in our body. This relieves our body from pain and mental stress.
