A Hear-say Riddle...
I've been told of a valiant woman,
whose radiance reflects the heavens. She's
never stationary, for she has visited many
people at various times. Many find her and
lose her again. Others, who have not known
her, discover and share a permanent affair
with her.
She's a spark of enlightenment, often
causing people to do extraordinary deeds for
fellow men, God, or country. Spiritual devotion
evokes her image. Often, it is profane love
that initiates her, and when she's invoked,
history can change.
What is her name?
