one more thing      we can take responcibility of our own actions and can do whatever is possible within our capacity     ant that is connecting with the super conscious   which comes mainly through three factors: faith, purified energy of body
[ through truth, right food, thaughts, speech, conduct and dutifulness] and dissolution of ones individual ego.

But we cannot take the responcibility of others actions    and as jigyasu says   " destroying all the Karmas of all the souls will stop rebirth and hence stop evolution"  so the life on earth will go on and there will always be unspritual people and as ell as spritual being .......

true sir  
like michio kaku says we are type 0 civilization, sucking on petroleum coal etc.
evolving to type 1 harnessing other vibrational energy
like tesla please read ( http://uncletaz.com/library/scimath/tesla/vedictesl.html )
one super article. tell me if u like it.

and could this transition be this 2011 thing? the mayan evolutionary calendar? a transition for which a some ethical sense is required?
like the movie from 1951 "the day the earth stood still"?

also as kripaluji maharaj says spiritually evolved beings who have these mathematics of prakriti under their command,
can take rebirths to help the unevolved. to dissolve resistance. to realign them.

I am sorry you 2 are just not getting it.....

It is day one of human existence.  The person dies and their soul goes on.  They return.  Why then mathematically do we have more than 2 people on earth?  One and One = 2.

Sorry if this finite mathematics bothers your theories.  But the facts remain it just doesn't add up.  

We can name the spiritually adept.  And probably make an even longer list of the spiritual uneducated.  The fact is we seem to have a rise in crime in most big cities.  That is a clear indication of lack of spiritual growth.  So where are all the spiritually adept?  

With even all that, I can say I witness the rise of consciousness of many to spirituality.  That is also happening through human agency.  Consciousness (out of which all is created) will rise to a more sincere level and that will change human society.

Speaking as a child of the 60s (as I'm sure spiritalk is) we saw such a surge of inquirery. People searched for knowledge - I know I did but it all evaporated, apart from 1 or 2 of us, the world carried on, wars, disasters, famine, crime all grew in spite of what we thought we knew.
I have totally diiferent world view now at the big end of the telescope to what I did when I looked through the little end.
Nothing has changed for the better and it never will, sorry.
