I am currently reading a book written by a Baha'i scholar, Jamshed Fozdar, who has been acclaimed by the World Buddhist Fellowship, the Southern Church, and other Buddhist orders! He dissects the Suttas or Discourses of the Buddha and presents to the reader the inescapable facts contained in the Tathagata's own words acknowleding His Divinity, the concept of the Supreme (i.e. God), and the true nature of the soul. I think it is highly relevant for anyone who is trying to find a bridge between Buddhism and the Abrahamaic ('Western') religions.
Jonzo, please read Sutta of "The Two Brahmins" as one perfect example of the Buddha acknowledging Brahama, and in fact says He is the Way to Brahama (i.e. Brahamayana)! The problem is interpreting the correct context of the Buddha's language. Buddha Gautama expressed the "Unseen Brahama" to be Infinite and non-associated with anything conceptualized or perceivable.
Here we can read some of the proofs that the Buddha acknowledged the concept of the Absolute or the Supreme from the Discourses:
"There is, O monks,
an unborn, unoriginated, uncreated, unformed.
Were there not, O monks,
this unborn, unoriginated, uncreated, unformed,
there would be no escape from the world of the born, originated, created, formed.
"Since, O monks,
there is an unborn, unoriginated, uncreated, and unformed,
therefore is there an escape from the born, originated, created, formed. (Discourse on The Three Characteristics and the Uncreate, verses 12-13)
And another Discourse we read: '"Kutadanta said:
"I am told that thou teachest the law,
yet thou tearest down religion.
Thy disciples despise rites and abandon immolation,
but reverence for the gods can be shown only by sacrifices.
The very nature of religion consists in worship and sacrifice."
"Verily I say unto thee:
The Blessed One has not come to teach death, but to teach life,
and thou discernest not the nature of living and dying.
"This body will be dissolved
and no amount of sacrifice will save it.
Therefore, seek thou the life that is of the mind.
Where self is, truth cannot be;
yet when truth comes, self will disappear.
Therefore, let thy mind rest in the truth;
propagate the truth, put thy whole will in it, and let it spread.
In the truth thou shalt live for ever.
"Self is death and truth is life.
The cleaving to self is a perpetual dying,
while moving in the truth
is partaking of Nirvana
which is life everlasting." (Discourse on Identity and Non-Identity, verses 5;12-14)
If we read these discourses in their entirety we discover that the Buddha was in fact not denying the soul but in fact He says there is "life everlasting" (i.e. eternality)! Also, to re-emphasize, if we diligently read through the suttas, such as in the 'medium discourses' of the Majjhima-nikaya, we find the Buddha affirming that His Dharma (Religion) is (quote) "an exaltation of the Absolute", meaning beyond mere mortal ken, and that He is at-onement with the "Uncreate" or the Absolute/Supreme. Continuously He describes the Absolute as absolutely unknowable, unattainable, and incomparable in essence! He also stated that all things proceed from (quote) "one Essence" and therefore all things exercise according to (quote) "one Law"!
Please consider some of the Writings of Baha'u'llah and Abdu'l-Baha to see the Baha'i philosophical perspective on these metaphysical issues, which are in accord with the Dharma of the Buddha:
"Were the eye of discernment to be opened, it would recognize that in this very state, they have considered themselves utterly effaced and non-existent in the face of Him Who is the All-Pervading, the Incorruptible. Methinks, they have regarded themselves as utter nothingness, and deemed their mention in that Court an act of blasphemy. For the slightest whispering of self, within such a Court, is an evidence of self-assertion and independent existence. In the eyes of them that have attained unto that Court, such a suggestion is itself a grievous transgression."--Kitab-i-Iqan, pg. 180
" Regarding the statement in The Hidden Words, that man must renounce his own self, the meaning is that he must renounce his inordinate desires, his selfish purposes and the promptings of his human self, and seek out the holy breathings of the spirit, and follow the yearnings of his higher self, and immerse himself in the sea of sacrifice, with his heart fixed upon the beauty of the All-Glorious."
and...
"As to the reference in the Arabic Hidden Words that the human being must become detached from self, here too the meaning is that he should not seek out anything whatever for his own self in this swiftly-passing life, but that he should cut the self away, that is, he should yield up the self and all its concerns on the field of martyrdom, at the time of the coming of the Lord."--Selected Writings of Abdu'l-Baha, pg. 207
and...
"Until a being setteth his foot in the plane of sacrifice, he is bereft of every favour and grace; and this plane of sacrifice is the realm of dying to the self, that the radiance of the living God may then shine forth. The martyr’s field is the place of detachment from self, that the anthems of eternity may be upraised. Do all ye can to become wholly weary of self, and bind yourselves to that Countenance of Splendours; and once ye have reached such heights of servitude, ye will find, gathered within your shadow, all created things. This is boundless grace; this is the highest sovereignty; this is the life that dieth not. All else save this is at the last but manifest perdition and great loss." SWAB, pg. 76-77
On a mystical level, I refer to the Buddha's metaphysical explanation of the 32 Planes of Existence, which according to the Blessed One the Buddha the last stages of complete enlightenment there is an engulfment in "Infinite Light" and "Infinite Nothingness". Again, the doctrine of Anatta is to describe the TRUE nature of the soul and not to deny our true purpose and existence! He asked a doubting brahmin where does Truth lie, to which He was answered that it exists no-where in particular, and so the Tathagata asked if then there is no such thing is Truth merely because you cannot place it anywhere.
