Then my friend, you are a better tea brewer than I. I have had abysmal experience when brewing whites.
I just can never gauge the temp! ARGHH!
I wouldn't go that far, nor even dream of suggesting it. I was basically agreeing with you that an yixing is just another, albeit refined, brewing vessel. A pot is a pot is a pot, even if it is (as my daughter likes to say) "one of daddy's pots made from magic dirt".
In one of his articles, the esteemed Hobbes, who brings an uncanny level of erudition to his tea reviews, once used the allegory of the aspiring archer as it relates to the zenlike progression of tea brewing. First you think, count, and measure; eventually you just know what to do. You know the amount to use without a scale. You know the temperature of the water without a thermometer. You know the time without a clock. You simply know. When you know all of this without having to give it a thought, you've achieved a higher level still.
Now although I agree with this sentiment entirely, I think it's somewhat oxymoronic to "overthink zen", so I'll add the addendum that the same can be said for that perfectly cooked steak that arrived at your table. You may poke and prod your steak, or even (gasp) stick a thermometer into it, but the accomplshed cook just knows when it's right, even if he's a toothless, illiterate, illegal immigrant laborer (exactly whom do you think cooked that steak for you, Andre Soltner?) two steps removed from the bread line who has never even heard the word zen. Advanced skill sets are just as impressive and transcendental in the absence of any associated mysticism.
I know little about brewing tea, and nothing of archery, but I do know a bit about sharpening knives. The goal is similar- perfection that is unattainable, only asymptotically approachable. By dint of constant practice, the goal eventually comes within view, whether it's drawing a bow, cooking a steak, or brewing a cup.
