Prompt: In ancient Rome, it was considered noble for nobles to wear purple robes. As the successor to the throne, Aurelius discovered that spending energy on dressing up and enjoying luxury would only wear down his will and become a slave to desire. He learned that the Stoics advocated frugality and pride in wearing short robes. So, like the Stoic philosophers, he began to stay away from sensual temptations and put an end to luxurious life. He took off his robe and wore short robes all day long regardless of his status. He did not sleep on the noble bed, but slept on the floor. Lacking clothes and living an ascetic life day after day, he was regarded as an alien by the upper class society, but he regarded frugality as spiritual practice and enjoyed it as much as sugar. Kitano Takeshi once said: \"No matter how glamorous a person is on the outside, after peeling off a layer of skin, only a bunch of desires are left.\" Human desire is like a bottomless pit. Our hands are constantly asking for things from the outside. If we have something, we still want to have it. What we have is too little, and we cannot fill the abyss of desire. Aurelius reminds us in Meditations: “Stop being a puppet led by various selfish desires.” A person does not need much in his lifetime. I can't sleep in a bed three feet tall, and I can't eat three meals a day. Excessive material pursuits will only make us exhausted and lose the focus of life. Only by knowing how to restrain our desires, live a modest life, and keep material things to a minimum can we free up energy and live a good life of our own.
