Four stones stand as the symbols for four elements of nature: water, wind, fire, and soil. Combined together they possess great power. It is not accidental that in the time of such modernized technologies and possibilities humanity once again has to turn to nature for help.

And only things that exist forever, like nature and love, are of major significance. All the rest is not everlasting.
