Harlan Tarbell,
in his introduction to The
Tarbell Course in Magic writes:
Hubbard, himself, was a great
teacher. Those at whose feet he sat, in turn sat at his feet.
he taught the love of man for his work; that every man was born
for SERVICE and the greatest man was he who served best. Like
Arthur Frederick Sheldon he believed that MASTERSHIP is doing
the right amount of the right things, in the right way at the
right time, in the right place, the right number of times, and
always in the right spirit.
