Vkrti means 'against Nature' and it represents the disturbance in our Nature (Prakrti) as it pertains to Dosha (Vata, Pitta and Kapha). I think it is important to say that all imbalance happens as a whole to all three dosha but often there are one or two dosha that lead the way. Is your own ecosystem suffering from dryness, heat, heaviness, lightness, stickyness (damp heat) or cold?
