Diamond introduction: Wide at the top and narrow at the bottom, standing in front, this is diamond. Diamond symbolizes both wealth and strength. From the appearance, the shape of this boulder is the same as that of a diamond, hence its name. This platform is called the Four-Dimensional Platform. The so-called four dimensions are the four directions of east, south, west and north. In Buddhism, the four dimensions have an immeasurably large meaning. When people sit there, gods are everywhere, their hearts follow the Buddha, and their merits are immeasurable. This statement comes from the fourth chapter of the "Diamond Sutra": "Subhuti, the four dimensions of space above, below, south, west and north are measurable. Can't you think about it? No, World Honored One. Subhuti, if a Bodhisattva gives alms without abiding appearance, the merits are also like this. It is inconceivable." "It means: East, south, north and west, there is a vast void above and below. It is impossible to imagine how big this space is. Then, when a Bodhisattva makes a donation, he cannot just seek appearance. If so, the merit he obtains will be as infinite as space. Standing on this four-dimensional platform, we should not only think about wealth, but also have a charitable heart.
