The first person singular seldom crept into the Master’s speech
The first person singular seldom crept into the Master’s speech. He once told group of New York friends that in the future the words ‘I’ and ‘Me’ and ‘Mine’ would be regarded as profane. Lua Getsinger reported that one day she and Georgie Ralston were driving with the Master. He closed His eyes and apparently fell asleep. Lua and Georgie talked on, probably about their own concerns, for suddenly the Master’s eyes sprang open and He laughed. ‘I, me, my, mine: words of the Devil!’ He said.
