Word prakriti is derived from two words- PRA + KRITI. Pra means the beginning or source of origin and kriti means to form. Combined meaning of prakriti is natural form or natural source. Word swabhab, sharrir and uttpati are used for prakriti in vedic litrerature. Prakriti is our body constitution. Every human being is born with definite genetic, constitution, determined by three doshas and environmental factors. Every human being is unique in shape and size. Physical, psychological and spiritual aspects are also different. Purusha a complete combination of dosha, dhatu, indriya, manas, budhi and atma. Every human body has panchmahabhuta, tridosha and triguna and all these are decided at the time of birth. Prakriti associated with physique, physiology and psychology is "DEH PRAKRITI" and parkriti associated to three gunas (satva, raja and tama) is called "MANAS PRAKRITI".
