confusion happens because i'm dealing with something that cannot be understood completely...or put into words..or proved by myself to someone else...excuse me for being a little confused when trying to describe Waheguru lol...
what are you saying here...it doesn't mean anything...its just words...so you think i'm just having moments of self understanding, which get longer and longer...what is this? realization, self understanding, awakening...whatever the word used...something happens..and i get my proof...call it what you like
its all words until you're there, experiencing it first hand
to prove something is being able to show it or guide someone else to the same experience.
its proven to me...and i'm telling you if you want proof do what SGGS Ji says and you'll get your proof.
i can't prove that the apple i ate was sour...i have to ask you to also eat it 
why are you so interested in being able to prove it...is it not enough for you to obtain the proof for yourself?
you're like a person that wants everyone to tell you what a certain holiday destination is like...when the best experience would be...pack you bags and get on a flight dude..lol
SGGS Ji tells you where to by the bag...ticket...boarding zone, time of arrival at destination etc etc...
on the question of other worlds...it can be proved to you...if waheguru shows it to you...if you have the right intentions...
oh dear oh dear
waheguru Will, waheguru flow...involves true selfless love as the base current...if we act in this 'naturally' we are vibrating at the same frequency. the Ego (which gives us this individualized experience) tends to bring anger, attachment, greed, lust into the picture...manmuck is one who follows such thoughts and turns them into actions which thus have their negative effects....gurmuck follows the heart more often than not, whilst fighting to rid the effects of the negative traits within them)
Waheguru is in control because all the above happens in His rules...as you sow shall you reap...go with the flow of current, love, compassion, forgiveness, patience, perserverence etc etc and you glide a lot easier...or flap your arms around in the current with negative traits and cause waves and ripples and tsunami's...physically manifested or mentally manifested...
this is how i see it at the present moment...
