I had a fantastic discussion with a friend (former client) on the weekend and for the first time since I've known her, she contemplated her Prakruti. The topic of discussion was comparing your being to others that seem to inhabit the qualities you desire. In this example, a Vata/Pitta desired the Kapha qualities of solid, calm, contained.
You cannot change your constitution. If you came into this world with, say, 20% Kapha qualities as your Prakruti, that's the portion that will keep you in balance. I know this struggle from my own early trials. As a student once you hear about the wonder that is Kapha -thick skinned and moving slowly on this earth - you tend to find yourself immersed in oil and grain and all things heavy in an attempt to "bring it on."
I soon found out about congestion and very quickly too (my Vata is quick to adjust).
We start off comparing. You may hear other students comment on the beauty of a particular person's constitution. It's like a mannequin - something to hang an idea on, but the clothes will always look different on you.
We begin by finding the edges of our doshic constitution - reflecting the Sakskrit word upasaya meaning trial and error - and eventually we hone it down to our own unique version. At that point external validation is no longer needed and your innate feelings and triggers are honoured and have space to be heard.
Another former client I recently chatted to (and Ayurvedic student) also made a comment that others are always asking her what she does, so they can emulate her to be able to glow like she does.
Ayurveda can be seen as a self-realisation process. Once you're good with the disease portion of the philosophy, I highly recommend sticking with the journey. Your mindset shifts from reacting to functional imbalances to noticing when you're in your personal rhythm and the shift of awareness that happens when focusing on your best self.
