Two verses of Bhagavat Gita
IMHO, Dharma,artha, kama are wordly karmas and the Universal
laws are Sathyam(sathyam bhoothahitham priyam) and Ahimsa(Ahimsa paramo Dharma)
guiding these karmas, for its(Universe'/Nature/Prakriti's) self preservation.
If you think deeply ,all these immutable laws including Laws of Karma are for
its(Universe/prakriti) self adjusting and balancing and therefore for its
preservation , survival and continuity.If these rules are violated in some instances ,then
the self-balancing kicks in.These violation of eternal principles are
Exceptions proving the Universal Rules of Sathyam and Ahimsa. But When Rakshas
like people,do gross violation of these first principles,huge fight back by
Dharma happens killing Hitlers to restore the Universal Balance for its
survival , preservation and Continuity.This happens due to Bhagawan's sankalpa of Dharma
rules, when he created this prakriti.-Dharmo Rakshati Rakshitah- and bestowed these Rules to it.
Above is a kind of explanation to Bhagavat Gita sloka, Chapter 4 Verse 8
"paritranaya sadhunam vinashaya cha dushkritam
dharma-sansthapanarthaya sambhavami yuge yuge".shuni chaiva shva-pake cha panditah sama-darshinah
