This famous Buddhist saying contains profound philosophical thoughts, and most people, including scholars, like to make fun of it. They think that color refers to women, and emptiness is nothingness or nothingness. They say that a monk who sees through the world of mortals and regards women as nothingness or nothingness becomes a monk. In fact, color is not feminine, and emptiness is not nothingness. "Color is emptiness, and emptiness is color" comes from Maha Prajna Paramita Heart Sutra. It turns out that this is an important idea of Buddhism. Simply put, color refers to everything that can be seen or invisible, and these phenomena are all human illusions. Emptiness, as mentioned above, is a variety of factors and reasons that produce phenomena, and it is the essence of things. For example, if an article is to be presented to readers, it first needs people's thoughts, paper and pen, and media tools. Can not be established independently. To put it bluntly, the appearance of the article is "color", and the reason for this "color" is "emptiness", such as people's thoughts and paper. If people don't want to write articles, or don't have pens and paper, they won't produce articles. Therefore, there is no male or female color, and there is nothing. Color is empty, which makes people realize the phenomenon of things and that many pains and troubles are illusory. Empty is color, so people understand karma and the cycle of good and evil by the nature and karma of things. The so-called: knowing the cause of the past life, the recipient of this life is, knowing the fruit of the next life, and the doer of this life is. It is the best explanation of the relationship between emptiness and many factors.
Only by recognizing the karma and the cycle of good and evil of "color is empty, and emptiness is color" can people be kind to others with their own personal virtue, truly care about everything in the world, and achieve detachment and liberation from suffering and troubles through their own practice and "abstinence, determination and wisdom" of "Tao". In this process, Buddhism also noticed "sadness". The so-called great compassion is probably equivalent to the "benevolence" of Confucianism. Generally speaking, "color is emptiness, and emptiness is color" is the basis of persuading people to be good.
