that would definitly make you a vata/kapha.........

are you saying, that prakriti changes constantly -from morning to evening and winter to summer. then it shouldn't be called prakriti, should be vikriti. prakriti by definition is 'original make'.

I don't know what books you've read, but I suggest...

The Textbook of Ayurveda: Fundemental Principles ~ Vasant Lad

all three doshas (Vata, Pitta, and Kapha) can manifest in both positive and negative ways - here is an online brief description of them, if this helps:
ayurveda.com/online%20re...tributes.htm

Dosha actually means imbalance, the positive aspects relating to bodily humors i.e. Vata Pitta and Kapha are the normal functions in the body and mind that each governs. Basically Vata is composed of Air and Ether and governs communication (nerve tissue), electrical and chemical impulses, and movement like peristalsis. Pitta is composed of the luminous and liquid factors or fire and water and governs all transformative processes including digestion, assimilation both bodily and psychologically. Kapha is composed of the solid and liquid factors, or Earth and water, and is responsible for all of the structure and stability that the physical body is composed of. Imbalance accurse when we have excess of any of the five elements, like excess fire in any form increases Pitta, excess air or wind in any form increases Vata, and excess earth or anything with its qualities increases Kapha.
