A semiotic study of Ganga Aarti in Varanasi is a work that defines the communicational aspect of rituals involved in deity worship. Here the deity is river Ganga and the message it communicates is the message of environmental peace and tranquility. A communication strategy has been developed to create awareness among masses about the cleanliness of the river through Ganga Aarti. A river that has been flowing through ages communicates something and we need an ear to listen to that.
