rocklad, nice to see you're not being a perfectionist, although you are perfection.
Remember good, better, best? You can answer your own yin yang water questions; can't you?
Master Lin says radiant or conductive heat is better energy than microwave. But boiling water and cold water is better yin yang water than a mix of cold and cold.
If you get to the black sesame tea directions, you can yin yang it. I do. So can you use hot tea water in yin yang... of course. But if it was best Master Lin would probably directed us to make and drink yin yang tea.
If you don't have a spring, with nice clean cold water, bubbling in your back yard, then use the best water you do have.
I feel that the yin yang water is the best thing you can drink to help balance your bodies qi. Tea, honey, black sesame seeds, and other things have their own special qi, but the best for balance in yin yang water.
You are perfection.
