"What then is it?...Who Then is It?"

...etc.

from The Book of the Coming Forth of Day, Plate X, (Budge trans.), sacred ancient Egyptian text.

Note. With respect to the WHO part of this, it may be
well in certain threatening circumstances to remember
to ask whether or not this person's mind is on fire
with demonism (hence highly irrational.)
If so then he is someone you naturally would want
to treat with due care and wariness.
