From a letter written by Prof. Huston Smith in 2004:
"It is only of late (perhaps in the last year or two) that I seem finally to have made my peace with the TU [Transcendental Unity] doctrine. It became clear to me that what I had found troubling was not the doctrine as such, but certain misconceptions associated with the doctrine, which not a few of its proponents seem to hold.
The problem, as I see it, is that one is tempted to conceive of that ‘transcendent unity’ as a doctrine in its own right. Typically one conceives of it in advaitic terms, thereby reducing that stipulated superdoctrine to an abstract formula of ‘nonduality’ which is supposed to embody the quintessential truth of the religions. Yet in truth a ‘reduction’ of this kind constitutes a betrayal of tradition, beginning with the Hindu tradition itself, which insists upon its six classical darshanas, and moreover counts advaita as only one of several Vedantic schools. What is more, it recognizes that the actual truth of advaita Vedanta cannot be expressed in words or grasped this side of nirvikalpa samadhi – which is just what the authentic doctrine of ‘transcendent unity’ likewise insists upon.
The problem with the TU doctrine, then, is that it is prone to be misunderstood. A Promethean temptation befalls us, an overweening desire to lay claim to an understanding which by right is proper to God. We have had occasion to see with horror! where this can lead.
Meanwhile, however, I am fully convinced that there IS a transcendent unity of which every authentic religion constitutes a manifestation willed by God. It seems to me that this transcendent unity is indeed ‘the pearl of truth’ enshrined within every religion, which the faithful are destined to discover and take possession of at the end of the road, when they shall have, Deo volente, attained to what Christianity terms theosis; for indeed, that truth is no longer a matter of doctrine, of theological or metaphysical conceptions, but is God Himself: ‘I am the truth’, said Christ.”"
