It seems to me, after reading about the higher dimensions of the world's major sacred traditions, that they are all based on the same metaphysical principles and that their practices lead their followers to the same Truth or liberating experience. If you read the words of, say, Meister Eckhart, Huang Po, Ibn Arabi, Longchenpa, Adi Shankara, Rumi, Lao Tzu, the Cloud of Unknowing, Plotinus, or any other sage from the world's major sacred traditions, it seems to me that they are all describing the same truth, flavored or "colored' as it were by their own personal theology or spiritual culture. It seems to me that all the major differences of this experience are word based and conceptual--they are attempting to formulate a philosophical tradition or description of an ineffable reality or experience as best as possible, which of course must be done to at least some degree if they want to lead their followers to the Truth. They are so many fingers pointing to the moon, but none can claim (in my opinion and in that of the Traditionalists) to be the only finger pointing to the moon or worse yet, the moon itself. They are all so many paths up the same mountain, but the peak is one. I suppose this picture can accurately describe the situation:
Now, from what I've read, Buddhism likes to deny this. It likes to say that all of these other experiences of an "ultimate reality" are still based in samsara, and that they must be transcended. But is there really a difference between the God of Meister Eckhart or Allah of Rumi or the Tao of Lao Tzu or the Paramsiva of Abhinavagupta and that of the deathless state Buddha experienced? Isn't it more likely the case that "Tathagatagarbha" or "One Mind" or "Suchness" of Buddhism is really the same as these others? That what the Hindus call the Self and Buddhists call "non-self" are just different conceptual formulations of the same experience that is ultimately beyond words?
Personally, I think it is true that these different traditions may have more accurate philosophical or theological expositions of what this "ultimate reality" or Truth may be, but does that really negate all the others? Can we really say that the Taoists or Sufis or various Hindus are having lesser experiences or are in contact with lesser truths than the Buddhists, who are the only possessors of the right way or the Truth? Isn't that a bit arrogant? Is there really any way of verifying that these examples of gnosis in other traditions are not the same as those of the Buddhists? I don't think so, but I'd like to hear what everyone else thinks.
