 Dehaprakti (body constitution)

       By them (the dosãs) which are present in the sukra  and ãrtava  at the time of commencement of life, there arises three kinds of prakti (human constitution) just like poisonous worms arise from poison; they (constitutions) are the heena (poor, weak) the madhya (medium, moderate) and the uttama (best, strong) from each (of the ( dosãs) respectively; that constitution arising from equal proportion of all of them (the dosas) is the samadhatu prakrti, which is ideal; those arising from combination of two doäs are nindya (denounced)

             The male seed is the sukra (spermatazoon - some times the term sukra also used to denote both male and female) and the female seed is the arthava—( the ovum). Both these unite together (fertilisation) and form the embryo and that is the commencement of life. The male and the female seeds produced in the body of the man and the woman, contain the tridoas. At the time of the union of the two seeds the dosãs undergo change in their proportion, either all of them might remain in equal proportion, or any two together might become predominant or any one doa only might become predominant.

              These conditions greatly influence the nature of the embryo in its characteristic features, which becomes known as Prakrti of man (natural human constitution). Thus seven kinds of prakrtis get formed, three ektdosaja (from any one doa seperately ), three dvafidvaja or sat-hsargaja (from the combination of any two dosãs) and one from sammira or sannipata (from the combination of all the three together in equal proportion). forms, ekadosaja are Ama (poor), the dvaikdvaja are madhya (moderate) and sammira is uttama (best, ideal).

        Further, even among the ekadoaja, the first one (vätaja) is hina (poor) the second (pittaja) is madhya (mode. rate), and the third (kaphaja) is uttama (best). The characteristic feature of these prakrtis ( constitutions) has been described in chapter 3 of Sãrlra sthãna. The example of poisonous worms is to indicate that though they are born from poison, they do not die of it, but Continue to survive, similarly the prakrti, though formed from the dosãs which are similar to poison continue to manifest in the person as long as he lives.
