Summarize this article in one sentence.
The first, and most basic Taoist principle, is that people and nature are not separate. Everything in the universe is part of the same system. As a Taoist, you can focus on oneness by being more selfless - pay less attention to your own needs and instead focus on others. For example, you can do something like serving in a soup kitchen. This is one way to remember that people with less than you are still connected to you. Just because everything in the universe is part of the same system doesn't mean there aren't distinctions. Taoists believe that there are two basic distinctions - described as yin and yang - in all of nature. Dark and light are part of the same system because they can't exist without one another, but they are also distinct. The principle of dynamic balance can be helpful if you're struggling in life. Remind yourself that according to this principle, happiness could not exist without sadness. The principle of cyclical growth is related to dynamic balance. Opposites balance each other out, but they don't usually occur at the same time. Instead, they move through cycles. So winter and summer balance one another, but winter is followed by summer and summer is followed by winter. Cyclical growth can help you understand where your life is going. If you're experiencing grief after the death of a loved one, remind yourself that happiness will eventually come. It might be a while, but grief will eventually give way to happiness. Taoists believe that because seeming opposites actually balance each other and cycle together, you can make one opposite from the other. A bamboo stick is a good example of this concept: In wind, bamboo bends, but doesn't break. By bending to the wind, the bamboo stick survives it, instead of staying straight and breaking in half. For example, if you're dealing with a difficult time, accept that it will be difficult and accept your grief or sadness. By doing so, you won't wear yourself out trying to be strong.

Summary:
Focus on oneness. See the dynamic balance in everything. Look for cyclical growth. Perform harmonious action.
