This verse from Walt Whitman’s poem “Song of the Open Road” is relevant to all thoughtful travelers, including those volunteering abroad:

From this hour I ordain myself loos’d of limits and imaginary lines,
Going where I list, my own master total and absolute,
Listening to others, considering well what they say,
Pausing, searching, receiving, contemplating,
Gently,but with undeniable will, divesting myself of the holds that would hold me.
I inhale great draughts of space,
The east and the west are mine, and the north and the south are mine.

I am larger, better than I thought,
I did not know I held so much goodness.

All seems beautiful to me,
I can repeat over to men and women You have done such good to me I would do the same to you,
I will recruit for myself and you as I go,
I will scatter myself among men and women as I go,
I will toss a new gladness and roughness among them,
Whoever denies me it shall not trouble me,
Whoever accepts me he or she shall be blessed and shall bless me.
