What are the four elements that are all empty?

The four elements are earth, water, fire and wind.

1. Earth is the solid material world we see, such as the bones and muscles of our body.

2. Water is the liquid material world, such as blood, water, urine, etc. in our bodies.

3. Wind is the gaseous material world, such as our breath.

4. Fire is temperature, such as our body temperature.

The four elements seem to be real existences, but when we analyze them, they are just particles of dust, that is, elements. That is to say, the material world is formed by the combination of causes and conditions, is an illusion, and has no eternity, so it is called the four elements are empty.
