Rasam, chaaru, saaru or kabir is a South Indian soup, traditionally prepared using tamarind juice as a base, with the addition of tomato, chili pepper, pepper, cumin and other spices as seasonings. Steamed lentils are added along with any preferred vegetables. Nowadays, all the seasonings required are combined and ground beforehand into rasam powder, which is available commercially. In addition to that , like Iced Tea and Cold Coffee, Rasam is also marketed commercially as Chilled Rasam.  
It is eaten with rice or separately as a spicy soup. In a traditional meal, it is preceded by a sambar rice course and is followed by curd rice. Rasam has a distinct taste in comparison to the sambar due to its own seasoning ingredients and is usually fluid in consistency.
In Tamil, rasam means "juice". It can refer to any juice, but rasam commonly refers to soup prepared with tamarind or tomato juice with added spices and garnish. Saaru in Kannada or chaaru in Telugu means "essence" and, by extension, "juice" or "soup". Rasa in Tamil means "taste" and also refers to juice. The use of kabir as an alternate name for this dish is most likely in reference to the Indian mystic poet, Kabir, whose poetry of enlightenment was probably associated with the intense flavors in the soup.
