As Plotinos's guardian spirit was a divinity, Plotinos kept the eyes of
his own spirit directed on that divine guardian. That was the motive of
his writing his book[6] that bears the title "Of the Guardian Allotted
to Us." In it he tries to explain the differences between the various
spirits that watch over mankind. Aurelius, who was very scrupulous
in his sacrifices, and who carefully celebrated the Festivals of the
New Moon (as Numenius used to do?) (on the Calends of each month),
one day besought Plotinos to come and take part in a function of that
kind. Plotinos, however, answered him, "It is the business of those
divinities to come and visit me, and not mine to attend on them." We
could not understand why he should make an utterance that revealed so
much pride, but we dared not question the matter.
