As I have said many times there are two kinds of people....Zoom-In types and Zoom -Out types. Zoom_In's tend to separate things out. They see differences. They dissect and label and segregate. The Zoom-Out's tend to integrate, see the similarities, take a holistic view.
Said Sriram, (ironically) dissecting and labelling humanity into two types. In fact, for years I tended towards your 'zoom-out' type of mind-set, which certainly provided what I thought were 'revelations' at the time, though on further investigation these proved to be inconclusive and no great guide to life. Aldous Huxley attempted the kind of synthesis you are talking about in his "Perennial Philosophy". This really ends up being simply vacuous.
Now, I won't deny that it is just possible that there is a "Somebodaddy deity/spiritual something" beneath all the "Nobodaddy" deities of the world, but these all differ so markedly in kind that I don't see much possibility of universal agreement. Deities can be immanent, transcendent or both. They can be prescriptive and interventionist, or simply distant and unconcerned. Or they can be the equivalent of the Oz aborigine Tikalick the Frog.
However, your analogy of zoom-in and zoom-out is useful. I'd express it as wide-angle lens and microscope. The trouble with the former is a mind becomes so 'spaced-out' as to be useless at ordinary social interaction and practicality: the trouble with the latter is the 'locked microscope effect', whereby a mind is unable to function except in the often trivial analysis of minutiae. Our minds need to be trained to move smoothly between both functions.
