This phase offers a detailed understanding of the group of symptoms that have surfaced the fact that all the doubts regarding the nature of the disease are eliminated. This sixth stage is characterized by severe impairment of dhatu function, serious damage to the Srotas (the vessels within each dhatu) and the complications that involves related dhatus. The entire disease process can be aggravated by the toxic side effects of the drugs that are used to cure it. At this final stage, many of the diseases become a bit difficult to treat completely.
