great post...you raise some very good points, and i agree wholeheartedly on many of them...
But i think you are basically saying that through sikhi no one can have a true experience of God (an undeniable personal experience of God) whilst alive in this life...within themselves (like Gurbani so clearly says)....lets be honest, you've made it very clear that's what you believe...and that is the exact opposite to what Gurbani says...end of.
Because lets face it...that would undeniably be downright crazy...airy fair, hocus pokus kinda stuff...the world would laugh at such a person... lol
I Thank God/Gurbani/Guru JI that everything Guru Ji says is absolutely True...because like many people on this forum have realised through the Grace of Guru...
God CAN be realized within oneself....and it is pretty wacky stuff...but only to the one that doesn't believe...to the one that does, they have come across something so Wondrous within them that they cannot even describe in words...
Call them Wacky...Call them stupid...that is fine...because Gurbani also states that the world will call them crazy...
and they are crazy...crazy in love with the only thing that will remain and forever exist...
Gosh...i'm soo damn crazy...and i love being crazy...
the truth seeker will always follow his heart when the people around him/her label their search for God as Vedic (i still dont know what that is), mystical nonsense, hocus pokus, airy fairy, ...and they don't really mind because Guru Ji also tells us that will happen lol Guru JI seems to know everything...could Guru Ji really be the 'Searcher of all hearts...the knower of everything" ... this is getting way to wacky to even hold a straight face lol (sarcasm)
one last thing on the truth seeker, the truth seeker will always continue to inspire others to do the same...to seek the truth 
God Bless Ji...
