lymph chyle, thus flowing out of the heart, constantly soothes, maintains, and irrigates by transudation the body, and further contributes to its growth, and supports life owing to the dynamical effects of causes which lie beyond the ken of human understanding. The nature and course of this lymph chyle, which runs through the whole system, can be inferred from the growth, attenuation, or other modified conditions of the body
Now it may be asked, whether the Rasa, which permeates the entire body and limbs, and which by flowing through different chambers (visceras) of the body is thus in constant contact with the excreta and other morbid humours, is of a cooling (Saumya) or heat-making (Ágneya) potency?
The question may be answered by stating that, since the Rasa or lymph chyle is a fluid, and possessed of lubricating, vitalising, moistening, and nutritive (lit:—supporting) properties, it must be included within the class of Saumya (cooling) substances. The Rasa, though a Saumya fluid, obtains its characteristic pigment (Rágam) in its passage through the spleen and liver.
Authoritative verses on the subject:—The Rasa or the lymph chyle, coloured through the effect of the healthy normal dyeing heat of the body, obtains the name of blood. The Rasa is transformed into the catamenial flow in women which commences at the age of twelve and ceases at fifty.
