Human body is a complex type of wonderful machine, which has millions of functions, majority of them are voluntarily controlled and some of them are unvoluntary or self controlled. Millions of cells in the body are working day and night to produce energy and maintain the life. Lot of wastes are produced in this process at the level of cells. These wastes should always be eradicated from the body, otherwise they stick into minute channels of the body known as 'srotas' and start producing diseases. That is why, if we want to be healthy, it is necessary to eliminate wastes from the channels and no room should be given for accumulation of these waste products.
