In Whitman's poem, Leaves of Grass
, "There was a Child Went Forth," there are the folloing lines:
There was a child went forth every day;
And the first object he look’d upon, that object he became;
And that object became part of him for the day, or a certain part of the day, or for many years, or stretching cycles of years.
The last line also states a similar sentiment:
These became part of that child who went forth every day, and who now goes, and will always go forth every day.
