Through tasting the joys of existence in a new way - Sip by sip rather than gulp by gulp, one could discover calm and contentment, appreciate the perfection, the harmony, the natural serenity and the true aesthetic that exists in every moment and in every natural thing. Putting up no resistance, one would experience boundless imagination and aspire toward a peaceful and fulfilling lifestyle. Through a simple cup of tea one can realize the supreme true reality of TeaMind.
