A Blooming Tree
May Buddha let us meet
in my most beautiful hours,
I have prayed for it
for five hundred years
Buddha made me a tree
by the path you may take,
In full blossoms
Im waiting in the sun
every flower carrying my previous hope
As you are near, listen carefully
the quivering leaves are my waiting zeal,
As you pass by the tree
without noticing me,My friend, upon the ground behind you
is not the fallen petals but my withered heart
