The Four Great Essentials

The Buddha talked of four primary physical elements, what he called the four great essentials. The material elements qualities like color and sound and taste, smell. Now we hear this, you know, Earth, air, fire, water. Doesn't really seem to measure up to kind of how we now understand things scientifically. But there's something about this framework that is still tremendously helpful for us because it's a way of describing our felt sense of the material physical world.
