Buddhism says that "everything is empty", which is based on India's inherent thought, and then it is deepened and Buddhist, because the four elements of earth, water, fire and wind are cosmic physics, for example, mountains belong to the earth, oceans and rivers belong to floods, hot sunshine belongs to fires, and space airflow belongs to strong winds. If we turn them into human physiology, such as hair and flesh, blood secretion belongs to water, body temperature belongs to fire, and breathing belongs to wind; From the four physical properties, hardness belongs to big, wet belongs to big water, temperature belongs to big fire, and flow belongs to strong wind. However, in any case, the four majors belong to the material world after all and cannot summarize the spiritual world. Therefore, materialists regard the Big Four as the foundation of the universe, while Buddhism never agrees with this statement.
Hinayana Buddhism, because it is only empty without me, not empty and impossible, still believes that the four micro-"dharma" is true, although it is empty without objects. But Hinayana Buddhism is not materialism but pluralism, because the emptiness of Buddhism is not only empty to four, but also empty to five aggregates, and four is just one of the five aggregates. What is five aggregates? That is color, acceptance, thinking, action and knowledge. The former belongs to the material world, the latter belongs to the spiritual world, and the four are color connotations. Five aggregates are the law of life and death within the three realms, and only by leaving them empty can we transcend the life and death of the three realms. At the same time, due to the proposal of the five aggregates, it is proved that Buddhism not only says that all four are empty, but further says that all five aggregates are empty. More importantly, the focus of Buddhism is not on the four, but on knowledge, and the three collections of acceptance, thinking and action are also the foil of knowledge, which are used to show the broad and great functions of the spiritual world. Therefore, Buddhism is not only a materialist but also a materialist.
