Now to tea and the imperfect cup...
Not every cup has to be perfection. When the tea turns out to have bitter tones because it has been over-steeped or, on the other hand, too watery because it has been under-steeped, one might be inclined to self criticism.
The imperfect cup will lead you to experiment with water types and temperature, different kinds of teaware, and varying steeping times. When taken in combination, the variables to achieving the "perfect cup" will keep you busy, amused, creative, and alert.
Buddhists say that "enemies" ultimately do more to benefit us than do our adoring, accepting friends. The enemy gives us challenges, which when overcome, bring us to a higher level of self-mastery and awareness, and therefore closer to "enlightenment" or spiritual completeness. So it is with the imperfect cup.
Sip, engage, explore.....and appreciate every sip of your "imperfect" tea!
