g.)  And from Agni Yoga:

●  
… Indeed it would be light-mindedness to
think that the One Who revolted against

Light were a weakling. One must understand
that the Forces of Light refrain from
annihilating the enemy not because of
weakness but because of a desire not to
upset prematurely the equilibrium of the
planet
. Few are able to realize that the power
of the Creator of the planet takes into
consideration physical conditions. …
 
(Fiery World II, 7.)


●  
“They will ask you how it is possible to
reconcile
the threatening signs of the
destruction of the planet
with the possibility of
a harmonious and auspicious future
[?]

“The fact is that humanity has a free
choice
, Either to enter the new life, the age of
great discoveries, the Era of Happiness,
Or,
by the power of free will to choose catastrophe.

“Thus, people cannot complain that they
are deprived of a beautiful destiny, for it
is only their evil will that could lead the
nations to planetary cataclysms
.

“Free choice is man's birthright. It
provides endless possibilities, but people
do not care to apply their freedom in the
right way
. (Supermundane, 111.)
h.)  Plus from Benjamin Creme and Helena
Roerich
:

(
i)  “If we did destroy the planet, it would
have irrevocable consequences for the rest
of the solar system, and the future for
humanity would be dreadful indeed
. We would
have no planet to live on, and would have
perpetrated a terrible crime against ourselves and
the other planets.

“We would end up incarnating on some
distant, dark planet, not at all evolved. We
would have to start at the beginning, as we
were millions of years ago, and take again
the long slow climb upwards. It would be
unbelievably painful and restrict our
evolution for thousands, perhaps millions of
years
. …”  (The Gathering of the Forces of Light)

(
ii)  “Certainly, the Lords of Light are taking
all measures for the saving of the planet
from this dreadful destiny.
And if humanity
chooses destruction
, its better part (and are
there many such?) will be transferred to the
higher planets
.

The average mass will go to another planet
similar to our own, which will approach Earth in
case the explosion occurs. (At the moment this new
planet is still not visible.)
[…] But alas! no one
realizes what retardation in the evolution of
the majority of our earthly humanity there
will be in the event of the destruction of our
planet. What aeons will have to pass before
the new "Earth" will be able to provide
suitable bodies
!  ( LoHR I )
