Nature Sounds: Heavy Rain is a rain soundscape. Climbing to a mountain temple, you are greeted by heavy rain, and you continue over the rocks with new streams flowing around your feet.
Recordings like this are often used as background for sitting practice, or to mask household noise. One way to practice is to follow a single sound, such as rain on stone, until attention wanders, then return to it.
Many people find steady natural sound settling. It is a simple support for practice, not a treatment for anything.
