Waking

Kalidasa in the 4th or 5th century C.E. (translated by W. S. Merwin & J. Moussaieff Masson):

Even the man who is happy
glimpses something
or a hair of sound touches him

and his heart overflows with a longing
he does not recognize

then it must be that he is remembering
in a place out of reach
shapes he has loved

in a life before this

the print of them still there in him waiting
