Why is it called so???
Reminds me of a song by the same name in Lion King  

The druidic belief of Life Death Rebirth Cycle is listed on page 66
of 2nd Edition Dungeons & Dragons : The Complete Priest's Handbook
as : This cycle is most likely to exist
in campaigns which don't have
gods of birth , death , fertility and
rebirth.  In campaigns which do
feature such gods, the forces of fer-
tility and death are opposed, while
in campaigns where this cycle is
the primary force, fertility and
death are part of the overall cycle.
Therefore, if the DM has gods of
death and fertility in his cam-
paign, he may not have this cycle;
if he has this cycle, he may not
have these gods.

and it says on page 45 . same handbook:
Birth, Children
This god's interest is in the safe
and successful birthing of chil-
dren and, subsequently, their pro-
tection and nurturing.
His priests take their interests
to heart, and, because of the god's
protective aspects, tend to learn
fairly powerful combat magics.
One lesser god of this attribute
would be the god of Youth, repre-
senting children and youths of all
ages from birth to the verge of
adulthood.
Gods of birth, children, and
youth tend to be female.
The priests of this god are on
good terms with the priests of An-
cestors, Community, Fertility,
Healing, Love, Marriage, and Race.
The priests of this god dislike the
priests of Death, Disease.

and in the First Edition Deities and Demigods:
Chinese Mythos female Deity Kuan Yin
(goddess of mercy and child bearing)
{paragraph 2}
No  act  of  violence  can  be  directed  toward  her  by  any  being in the
universe. For example, she could walk safely through 500 different types
of  demons  and  devils  and  never  be  harmed.

And my the way I've been more sensually activist lately.. so the picture of
Aphrodite did look more appealing.. so uh thanks Aphrodite [D&D actress]
I won't bother the actual adorant goddess of huh male seeing arousal . . .,
I know she's married and I'm respectful about it.. I won't give any detail ..
So the Deities of Cycle of Life are prevalent as good and powerful Peace...

Maybe the druidic belief in human cycle of reincarnation {not game example}
will show all good and proper are old souls with long life and vigor soulfully. .

It was my statement ... thanks for the humor ... BlessedB Evard ., Summoner.

Why would you need an interest in children if the same was coming again and again?  It matters not into which body - that is not a cycle it is doing the same thing over and over again and expecting different results.  (Einsteins theory of the definition of insanity).

A cycle has continuity not regress.

Einstein was a creative genius , the circle of life  ,cycles do indeed exist , but not in a perfect circularity,  but in elliptical fashion  ,points of reference measured in lines ."circle of life" but yet defined as the web of life   and we are all part of this web ,but beware of the black widow who is also part of this web  which i have come to rename (sociality) or (the machine)  she will lure its mate in and multiple and then kill  .objective  is to move around the web  not getting to close so as too become victim and not to far as to off off the grid

OK A Circle where you don't get different "results" and Einstein getting fed up by dumb Naza nurses..
That's the definition of ubiquitous polite scientific tolerance against evil or sullen dishonesty.. Phlan.....

Humor .. could pagan minded have a "happy" holiday ./.   Thanks .    Evard
