Yin contains Yang阴包含阳

Look again at the symbol for yin and yang at the beginning of this section; do you see the white dot within the dark paisley swirl? Even within the darkness of yin, there is found a lightness of yang. And vice versa: within the white swirl is a black dot; within yang is always found yin. In the context of temperature we say that hotter is yang and cooler is yin: but slightly hot is yin compared to extremely hot. And extremely hot is yin compared to hotter yet, which would be yang. In the other direction there is cool and there is cold. Yang would be cool relative the yin of cold.

再看看在这节开始时阴与阳的符号；你看到在黑色旋窝时里有白点吗？即使在黑暗的阴里，也能发现阳的光亮。反之亦然：在白色旋窝里有黑点，阳里也能发现阴。对于温度我们说热的是阳，冷是阴的。但稍热比热是阴。极热相对于较热是阴，极热又变成阳。另一方面有凉和冷。相对于阴的冷，凉是阳。

In our yoga practice there are very active asana workouts, which we may call yang, but even within these relatively yang practices we can find relatively yin aspects; watching our breath mindfully while we flow through a vigorous vinyasa [2] is just one example.

在我们的瑜伽练习中有非常积极的体式练习，我们可以称之为阳，但即使在这么相对于阳的练习，我们也能发现阴的练习。谨慎地观察我们的呼吸，当我们通过精力充沛的vinyasa来串联时就是一个例子。

Yin becomes yang阴变阳

Just as we can detect yin elements within the yang aspects, we can also notice how yin becomes yang, and yang can transform into yin. These transformations may be slow and subtle, or they may be devastatingly quick. The seasons roll slowly by; they change imperceptibly. The yang of spring and summer transforms day by day into the yin of fall and winter. It is not possible to pick the exact moment at which one season becomes another, astronomical observations notwithstanding. But the transformation may also come quickly: the eye of a hurricane quickly brings calm, and just as quickly the eye moves on and the other half of the storm strikes.

当我们探索阴元素存在于阳的时候，我们也注意到了阴如何变成阳，阳可以改变成阴。这种转变可能是缓慢和微妙的，也可能是毀灭地快。四季缓慢变换：它们不能感知地改变，春天和夏天的阳日复一日转变成了秋和冬的阴。尽管有天文观测，从一个季节到另一个季节也不可能找到准确的变换时间。但也可能迅速转变，暴风突然变得平静，而很快另一场暴风又起。

In our own life we often experience both the slow transformations of yin into yang, and yang into yin, and the quick changes. We wake up in the morning; yin becomes yang. Sometimes our awakening is slow, leisurely; this is a slow transformation. Sometimes we wake with a start and jump out of bed, perhaps because we realized we overslept. When we work long hours for many weeks or months in a row (a very yang lifestyle), our body may seek balance by suddenly making us too sick to work (a very yin lifestyle), or it may gift us with a severe migraine to slow us down. Yang is quickly transformed into yin.

在我们自己的生活中，我们经常经历阴变成阳，阳变成阴的缓慢转变和快速转变。我们早晨醒来，阴变成阳。有时我们醒来是缓慢的，悠闲的，这是一个缓慢的转变。有时我们一下子醒来并马上起床，可许是我们意识到我们睡过了头。当我们长时间工作，如几周或者几个月（一个非常阳的生活方式），我们的身体可能突然生病（阴的生活水平方式）而失去平衡，或者它让我们严重的头痛让我们停下来。阳很快地转变成阴。

Yin controls yang阴控制阳

In this last example, we can see that if we stay too long in an unbalanced situation, the universe acts to restore balance. It throws us to the other side: our health may suffer; our lives may change. If we do not heed the need for balancing yin and yang, this transition can be devastating; a heart attack could be the balancing force applied to us. These imbalances are often referred to as either a "deficiency" or an "excess." We can have an excess of yin or a yin deficiency; we can have an excess of yang or a yang deficiency. The cure is to apply the opposite energy to control the excess or deficiency.

在这个最后的例子，我们可能看到如何我们在一个平衡的状态太久的话，自然变会帮助我人恢复平衡。它把我们抛向另一方面：我们的健康受损，我们的生活可能改变。如果我们不能听从阴和阳平衡的需要，这种转变是毀灭性的。心脏病发作可能是平衡力量作用于我们的身体，这种失衡通常是不足或者过度中的两者之一。我们可能阴盛阴衰，或者阳盛阳衰。治疗的方法就是提供相对的能量控制不足和过度。

In the Eastern world of the Daoists and yogis, [3] the need for balance is well known and understood [4]. In the West, the concepts of yin and yang are more foreign. We don't think in these terms; our lifestyles rarely reflect a need for balance. We seek it only when the universe forces us to pay attention. Fortunately, the idea of yin and yang is becoming more widely known here in the West. Let's look now at how these terms can be applied to our own bodies.

在道家和瑜伽修行者的东方世界，平衡的需要是众所周知和理解的。在西方，阴和阳的要领是陌生的。我们不认可这些术语。我们的生活很少考虑到阴阳的需要。我们寻找它仅仅当自然迫使我们注意的时候。幸运的是，阴和阳的概念在西方正变得广泛了解。现在让我们看这些术语在我们的身体力行上如何应用。
