To me every hour of the light and dark is a miracle. Every cubic inch of space is a miracle.
Source: 'Miracles', Leaves of Grass, Walt Whitman (poem first published 1856)
Genuine Whitman, from the poem 'Miracles' in Leaves of Grass: 'To me every hour of the light and dark is a miracle, / Every cubic inch of space is a miracle.' The quoted text matches the poem apart from line breaks rendered as sentences.
Dismiss whatever insults your soul.
Source: Preface to Leaves of Grass, Walt Whitman, 1855
From the 1855 Preface to Leaves of Grass, in the celebrated series of imperatives ('re-examine all you have been told at school or church or in any book, dismiss whatever insults your own soul'). Note the original reads 'your own soul'; the corpus text drops 'own', a small but real deviation from the printed line.
I believe that a leaf of grass is no less than the journey-work of the stars.
Source: 'Song of Myself', section 31, Leaves of Grass, Walt Whitman
Genuine Whitman, opening line of section 31 of 'Song of Myself': 'I believe a leaf of grass is no less than the journey-work of the stars.' The corpus text inserts 'that' after 'believe', which is a common quotation variant but not the printed wording.
All parts way for the progress of souls, / All religion, all solid things, arts, governments - all that / was or is apparent upon this globe or any globe, / falls into niches and corners before the procession /of souls along the grand roads of the universe.
Source: 'Song of the Open Road', Leaves of Grass, Walt Whitman (first published 1856)
Genuine Whitman, from the late sections of 'Song of the Open Road'. One transcription error to fix: the poem reads 'All parts away for the progress of souls', not 'All parts way'. Line breaks in the corpus text also do not match the poem's lineation.
