My chosen meaning:
The cherry blossom is a very delicate flower that blooms for a very short time. For the Japanese this represents the transience of life. This concept ties in very deeply with the fundamental teachings of Buddhism that state all life is suffering and transitory. The Japanese have long held strong to the Buddhist belief of the transitory nature of life and it is very noble to not get too attached to a particular outcome or not become emotional because it will all pass in time.. Saw a picture of something similar and loved it.
