ADD ME PLEASE ALSO The voice that beautifies the land!

The voice above,

The voice of the thunder

Within the dark cloud

Again and again it sounds,

The voice that beautifies the land.

The voice that beautifies the land!

The voice below;

The voice of the grasshopper

Among the plants

Again and again it sounds,

The voice that beautifies the land.
