Inking difference

A lost gram of ink touches color touches
       silk as it is learns to want  -  asks
       the silkworm: where to find the

warmth of your longing that begets the 
       eking of song?  -  asks the parchment: 
       which word sat heavy and which light

and how to tell them apart if the two insist 
       on being same?   will their difference 
       subsist if I ink them together as one?
