Mike,
Whew! This is the first time in my life someone has seen value in what I have written! Everyone else, everywhere, just says, “You are totally wrong and could have no portion of the truth, please go far, far away!” I kid you not! They all turn their backs on me, every one! I define religion as what comes from God, and spirituality as what comes from man. In defining his spirituality, man has relied on religion; this is true even of enlightened sages like Cohen, who keeps referring to an “oversoul,” and great saints like Mother Teresa of Calcutta, who keeps referring to the Creator. They sense a greater authority is present in religion, and so they fall into line, perhaps without realizing it. This authority is seen in the formal liturgies and ceremonies that have been introduced, which have profound unstated meanings, as well as in the magnificent architecture employed, to lift man’s considerations into zones of the spirit.
There are many signs of the unbridgeable chasm between Eastern and Western spirituality. One of them is that the West posits an embodied Creator, and the East states that the universe was created from within. Western mystics thus describe their experiences with reference to the Lord, giving thanks to the Creator, whereas in the East they typically take credit for their own existence. Then there is the question of where everything is headed. The saints look to a heaven after only one lifetime, whereas the eastern gurus look to total dissolution in the “All.” If you study the works of any mystic, East or West, you will find them always speaking in terms of their tradition. Even those who try to bridge the chasm, like the one you mention, fail because they cannot answer ultimate questions about motivation and destination, creation and destruction. Yes mytical experience is ineffable, but God has not yet revealed the correct paradigm, by which the East and West may be bridged. One would expect such a revelation may occupy a prominent place, in the Second Coming of Christ.
