"In my heart, the tiger smells the rose" is an immortal epigram written by the English poet Siegfried Sassoon, which comes from Meet Me, Past, Present and Future, and translated by Mr. Yu Guangzhong into The Tiger Smells the Rose in My Heart.
The fragment is as follows:
Dance with your dream-liberated feet? Dreaming of liberating your feet and dancing constantly.
In me the tiger sniffs the rose. There is a tiger sniffing roses in my heart.
Sigrid used the tiger to symbolize one side of human nature, and the rose to symbolize the other side of human nature. "Smell" just symbolizes their relationship, harmony and unity. It is intended to show that human nature has two sides, and the opposing human nature is harmonious.
