In Their Inmost Hearts

Life leads the thoughtful person on a course of many windings.
First the course is checked, now it runs straight again.
Here winged thoughts may pour freely forth in words,
There the heavy burden of knowledge must be shut away in silence.

But when two people are at one in their inmost hearts,
They shatter even the strength of iron or of bronze.
And when two people understand each other in their inmost hearts,
Their words are sweet and strong, like the fragrance of orchids.
