Sri Hari,
the point is about faith here. it is about the trust we have on the words of the Guru who advises us the way that we have to go. what ever else the scriptures declare, be it the Gita, Bible or the Koran, let it happen in its own course. Our bounden duty at the moment is to blindly follow the Guru's advise.
i would go on further to say, who knows what truth, really is, who really knows, if it is advaitA, or dvaitA or visishtAdvaita or what the Koran says or what the bible says or what ever the other great schools have to say, who can say?
It is purely and simply like resting all our faith on our mother, and rest our faith on her without any questions, whatsoever! We know, the mother will not fail us, no matter wherever she goes, she will protect us, she will give us what ever the best she has, what ever best she knows.
Without the mother (Guru), it is only going to be chaos, why to remain in a speculative realm? rather the words of the Guru who is verily the mother is the only thing that can be trusted upon blindly.
When we are under the shadow of the Guru, there is no question of what if... what He says, I do, and I leave all the "what if's" to the Guru!
This is the spirit that brings me solace!
