Camphor is widely used in Hindu religious ceremonies. Hindus worship a holy flame by burning camphor, which forms an important part of many religious ceremonies. Camphor is used in the Mahashivratri celebrations of Shiva , the Hindu god of destruction and (re)creation. As a natural pitch substance, it burns cool without leaving an ash residue, which symbolizes consciousness. In Hindu pujas ceremonies, camphor is burned in a ceremonial spoon for performing aarti.
This type of camphor, the processed white crystalline kind, is also sold at Indian grocery stores. It is not suitable for cooking and is hazardous to health if eaten.
