The sun only rises for free.

The moon is indebted to the sun
because it does not have its own light
so it does not rises for free.

The sea depends on the moon
and thus its ebbs and tides
so it is also not for free.

The waterfall depends on the earth's pattern
and it needs the mountain to fall
so it is not a free fall.

But, if we desire
the pure love
it can always be free.
