Let love melt in memory and pain turn into songs. And which poems does it come from Tagore?

My painful love!

May love melt in memory and sadness turn into songs!

It is painful to love someone and not be loved in return.

But what is more painful is that.

Love a person without courage.

Let that person know how you feel.

It only takes a minute to get a crush on someone,

It takes an hour to like someone and a day to love someone.

A person-but it takes a lifetime to forget someone.
