When your mind acts with no hindrance, that is Sangha. In Sino-Korean, we call that shil yong sam bo, which means real three treasures. If you drink tea with a clear mind, then in that moment, you become actual Buddha, actual Dharma, actual Sangha. In the Compass of Zen , it says that the treasure of Buddha means beauty, the treasure of Dharma means truth, and the treasure of Sangha means morality or goodness. Everyone has seen a beauty contest on television.
Many women come together and are judged on beauty.
That means the judges look for each woman's beauty, or mi. But they only look at the woman's body and face. If her face and body are beautiful, and if her actions are graceful, then this woman wins the contest. Usually our mind is filled with many kinds of ignorant thoughts, and that makes the mind seem ugly. If you practice hard and gradually take away ignorance, you get enlightenment.
