The message of this line is that when two people resonate with each other, while they might be separated physically, their hearts are still united. People might be kept apart by different kinds of obstructions that cause them to weep. But when they remain truthful in spirit, nothing can really separate them. After they experience the difficulty of separation, they are able to appreciate the true joy of union.
Confucius once said,
"Whether in charge of a government or being a hermit,
Or keeping quiet or making comment,
When two people become one in their hearts
They are as sharp as a knife that is able to cut iron.
They cherish the same idea and follow the same path;
Their words are like the perfume and fragrance of orchids."
