It wasn't until many years later that I understood Tsangyang Gyatso's poem.
He said.
First, it is best not to meet each other, so that you can not fall in love. The second is that it is best not to know each other, so that you can not miss each other.
It is a pity that I did not understand these principles earlier ten years ago.
Although regretful, I don't regret it.
Because I know that I once loved someone so deeply.
