Based on what you know of Walt Whitman's life, the lines that he wrote are A) I dote on myself, there is a lot of me and all so luscious, each moment and whatever happens thrills me with joy, I cannot tell how my ankles bend, nor whence the cause of my faintest wish, nor the cause of the friendship that I emit, nor the cause of the friendship I take again.
The other lines were written by Emily Dickinson.
