Looking at the stars in a down-to-earth way and looking up at the starry sky, people determine their unique coordinates in the world in the vast galaxy; Down-to-earth, people in the process of accumulating footsteps, moving towards the holy land in their hearts. People say that the earth and the sky are very different, and it is contradictory to look at the stars in a down-to-earth way. People will forget to move forward as soon as they look up, and they will forget the direction when they walk on the road. I don't think so. The blue sky overhead and the earth under our feet are isomorphic, which constitutes our living world and are indispensable. The sky represents hopes and goals. Looking up at the starry sky, people have the impulse to fly and their own little consciousness. The earth represents reality, life, down-to-earth, let people pursue what they want and move forward calmly towards their ideals. Walking between heaven and earth, people have dreams and reality, hope and life at the same time. Looking up at the starry sky, the infinite unknown gives people the courage to explore, and inserts dreamy wings for this creature walking on the earth. The change of the law of the sun, the moon and the stars day and night once brought people their own curiosity and impulse, and people began to be eager to know everything around them and their position in the world. Thus, from the theory that "the sky is round and the earth is round" to the shock of "geocentric theory", Gagarin went into space for the first time, Apollo landed on the moon for the first time, and countless people looked at everything from a rational point of view in different ways before science existed. Thus, from the Zhouyi in China, to the sculpture in ancient Greece, and then to the Renaissance, countless people describe the world we live in from a perceptual perspective in different ways, and art can continue. Science and art come from looking up at the starry sky, which has brought rich spiritual life to mankind, so people have a pair of wings that can fly to the unknown. Down-to-earth, let us have the pleasure of asceticism, let us have an ordinary and peaceful life. There is an old saying: "Better retire and build a net than fish in the forest." Down-to-earth, let's start weaving nets to harvest our dreams and reach a thousand miles in accumulation. Down-to-earth is also a simple attitude towards life. Someone once asked the secret of meditation, and the Zen master only replied, "Eat when you are hungry and sleep when you are sleepy." When asked why, the Zen master replied, "Ordinary people are not like this. Hungry, picky eaters, sleepy and demanding. " The same is true of people in reality. People are dizzy all day and ask for it with unrealistic fantasies, but few people can calm down and do what they should do now. Down-to-earth, weaving a net for people to capture their dreams. In our life, looking at the stars in a down-to-earth way has always been integrated and inseparable. Some people only look up at the starry sky, hold unrealistic ideas, deceive others and themselves at the same time, and even fish, but they don't know how to retreat. Some people only pay attention to their feet on the ground, but fall into a blind and ignorant situation, so that they spy on the sky with pipes, measure the sea foolishly, sit in the well and watch the sky, and miss the opportunity. If looking up at the starry sky brings us rich spiritual life, then down-to-earth life brings us a down-to-earth life. May we gallop freely between heaven and earth, and rely on the wings brought by the starry sky and the huge net brought by the earth to harvest our inner dreams and wonderful life. Looking up at the starry sky and down-to-earth, we can walk on our own roads calmly.
