Much that Meher Baba observed then in America seems to have served, metaphorically, for the setting forth of his teachings. This is suggested by the section entitled "Theory and Practice," on page 23, where he likens spiritually undirected thinking, talking and writing to the steam which escapes through the whistle of a railway engine. The whistling makes a noise, but no amount of it can set the engine in motion. Only by a different application of its steam can the engine with its train attain a distant destination. Likewise, without wisely directed discipline there can be no spiritual progress. Mere theorizing will never advance the disciple; it is practice, not theory, that produces results. This yogic truism is further emphasized on page 52 in "Knowledge Through Experience"; and, also, in a more subtle manner, on page 37 in "Tuition and Intuition."
