For, just as in the realm of the spirit, the reality of the
Bab has been hailed by the Author of the Bahá'í Revelation as "The Point
round Whom the realities of the Prophets and Messengers revolve," so, on
this visible plane, His sacred remains constitute the heart and center of what
may be regarded as nine concentric circles, paralleling thereby, and adding
further emphasis to the central position accorded by the Founder of our Faith
to One "from Whom God hath caused to proceed the knowledge of all that was
and shall be," "the Primal Point from which have been generated all
created things."
