IS THERE A HELL?

And speaking    of  hell,   does    such    a   thing   exist?

Only in the minds of disconnected humans. The animals don’t know of it.
Only humans who pinch themselves off from clarity. Wouldn’t you call
confusion a sort of hell? Wouldn’t you call lethargy a sort of hell?

People who have behaved in horrific ways, is there punishment when they
leave this earthly plane?

Humans are often disappointed when we tell them that is not the case. Your
punishment is self-inflicted as you deprive yourself of the Energy of Source,
which is available to you at all times. When you disallow that, it is very
unpleasant. But when you reemerge back into Non-Physical, you will leave
behind all doubt and fear, all grudges, all hatred, all misunderstanding. And you
will become a vibrational equivalent to all that this life and before has caused
you to become.
