It’s hard to explain with my poor english,
one of my friends understanding Japanese tells me that,
the title of this piece is from the first sentence of a very old song いろは (about A.D.1079),
this song also tries to tell a concept of Buddism - life is unpredictable and full of uncertainty , nothing is permanent ,
so my friend translates privately the title into “The glories(the prosperous) die away”.
Hope that it could help you .
