Apart from their participation in the Kumbh Mela, Sadhus usually live rather solitary lives, renouncing society and leading a monk-like existence, with basic food provisions and few possessions. Most Sadhus wear distinctly coloured clothes, to set them apart from the civilian population, while a number of Sadhus decline to wear clothes altogether, as they all used to do traditionally. Their distinct clothing, or nakedness, symbolises their renunciation of the mortal world and their dedication to a new spiritual existence. In a similar vein, on becoming a Sadhu, the holy man renounces his old name and receives a new one, indicative of his affiliation. Most often, however, they are referred to by the term Baba, which means, old wise man. The Sadhus spend their time in devotion to their chosen deity, the most popular of which is Lord Shiva, the Destroyer (Shaivite devotees). Vishnu, the Preserver, or rather his incarnations (Avatars) like Rama or Krishna, are the other most followed deities (Vaishnavite devotees).
