Where's the quote come from then? Cuz I assure you its origin is not ghandi Found it Bishop Beckwaith (probably a misspelling of John W. Beckwith, 1831-1890) in a newspaper from 1885:

Plant a thought and reap a word; plant a word and reap an action; plant an action and reap a habit; plant a habit and reap a character; plant a character and reap a destiny.
