You can't know enough in Ayurveda.
The reason for this is that to know yourself is a lifelong journey. And I'm sure you can attest, it took a bunch of experiences to get you here today. Some of that was uncomfortable, some moments of feeling at peace, but there can be no doubt that every single moment is an expression of you as a human being in this lifetime, the sum parts of the whole.
In short, you're an unfoldment of good vs evil stories.
So how can an online quiz capture that?
A quiz is a point in time. You see yourself in a point in time with the knowledge you've garnered until that point. So although the concept of Prakruti is static and never changing, your viewpoint of yourself is changing along with seasonal and daily shifts, unless you can access that state of non movement in meditation, and that's a chicken/egg situation.
For the most part, and shit I hate to generalise in Ayurveda, but in this instance I could confidently say that most people have a Vata disorder, to varying degrees of course, but when we break down the essence of Vata as movement then we can see how the movement through life is nothing but constant change.
The whole purpose of a yoga practise is to still the mind - yogas chitta vritti nirodhah (Yoga is the removal of the fluctuations of the mind. (Yoga Sutras: I, 2). Without this stillness it is difficult to see the surface below. To calm the Vata dosha is to assist in this journey. I cannot imagine my Yoga practise with Ayurveda; it's just made it so much easier to be objective. I always found the concept of capacity an interesting one. How far do you know how to go with anything in life? We're always looking to the star signs to tell us what's happening TO us, but there is a way to know ahead of time by listening in.
Have you ever read these full moon, new moon, eclipse astrological reports? I would like to see a film edit of a few of them bunched together. They all say that you need to go within. Spend time meditating. All of them. All of the time. My own little made up analysis of that is because these are junctions, just like the solstices, and equinoxes and dawn and dusk. All junctions are change and to sit quietly as the change moves through is to calm the Vata dosha. Hell for those of us that believe perhaps being alive is a junction of a different state at death.
I do an extensive intake and it's common enough that new clients will express difficulty in having answers to basic functions such as elimination or digestion. We don't look down and we don't look in. And we most definitely don't do this daily - but this is Ayurveda and everything else is but an intellectual discourse. So unless you're being trained to think in a different way - the way of self awareness - then you are most probably using the western med mindset with a bunch of new fancy language and herbs grown in India.
I don't advise people to read books on Ayurveda when they first begin because they confuse themselves. To know this art is to experience it - to see the doshas play themselves out. It's wearing your devil by your side, making friends with them and seeing the signs before they become issues. It's having rituals in Summer that are different from the Winter. It's taking into account the weather before embarking on your morning exercise. It's observing the qualities of the people around you and how they affect your doshas. It's being aware that the gaps from home to work and work to play are as important as the herbs or oil pulling or whatever else is purportedly Ayurvedic.
It's a way of being. It's a philosophy that sticks by you but requires a constant curiosity to stay alive. To activate prana requires relaxation and focus, ie to be ALIVE and VITAL requires relaxation and focus. I once heard, somewhere in some book on yoga, that to know the world you only needed to know the leaf of the tree (insert anything). I get it. It's not about adding more stuff to your day, it's about sinking in deep with what you already have. My newest analogy for Vata is the dragonfly, just skimming the surface, and if you let yourself fall into something you get to see the soft slow calm and hypnotic bottom of the ocean. Just choose one thing.
So take the quiz. I think they are fun and wonderful but you need to do them daily for at least a month and then each season. And then review them in hindsight to see how you trend. And most of all, be honest with yourself on how you're interpreting them - that last one can be tricky when you first begin because our fear monsters tend to be the boss when we're not aware. But know you have only just begun on a journey that seemingly has no end and since you are going to evolve whether you like it or not, you might as well be the host of the party.
