Dear Sumanth,
Let me congratulate you on deciding to ask questions. You have commenced a journey my friend, and you are in the best of hands. And thats NOT me!.........Its the wonderfully, intelligent folk you will meet here, IF you hang around long enough.
For starters, you have great advice from Sadananda, a Giant, in this area.
Let me, (still very much an ajnani), answer & hope not to delude you.
You ask WHO is the experiencer? So Vedanta uses the analogy of the Dream. In a Dream, you create the landscape, situations, and all the people therein. And there is also A YOU, in your own dream experiencing the happenings in the dream. So you may find murderers in the Dream & Condemn them..............Now here's the fun part. When you WAKE up next morning ARE YOU still going to condemn that murderer YOU saw in your dream?.........the one that you created? with your MIND
Now use that analogy of the dream to understand THIS WAKING DREAM. Your MIND & your senses, are causing you to believe that there is a real world, with real people, & real feelings..............and all the TAMAS, and you JUDGE & condemn (just like the sleeping dream), but here's the deal............THE REAL YOU, is watching the TAMASHA, in this dream, and the sleeping dream, AND in Deep Sleep. Your challenge (though easy) is to recognize this ONE CONSCIOUSNESS, that YOU ARE............& not confuse it with YOUR EGO,...........because YOUR EGO, will seem to GET IT,..........& you are back to square one..............meaning you have to realize that your mind and ego...........are ALSO YOU, & yet NOT REALLY, THE REAL YOU!...............I know this sounds like profound CRAP...........& thats why VERY VERY few people GET IT.
Now does THIS MEAN, that the world doesn't exist.........OF COURSE NOT.............this is the bone of contention (if any) in Vendantic circles.................IT EXISTS, but IT IS YOU,..........watching yourSELF, in this CREATION.......this is extremely hard for over Pavlovian-conditioned mind to understand...............& in fact THIS mind, will stand in the way (through intellectualism), to confound, the PROFOUND aspect of your OWN PRESENCE, in this PRESENT MOMENT.
I wish you well, my fellow DREAMER, but, I too am searching just like you...............but the GURUS are around, we need to be astute and observant of them.
