Thanks, gus. Your post reminded me that I've been meaning to get on
these boards and post somethng about Nisargadatta...
I've been reading I AM THAT recently, and have been struck by how
mutually supportive Wolff's and Nisargadatta's teachings are. They
really are consonant. In fact, I found it really useful to read I AM
THAT in support of Wolff's books because it adds even more power and
authority to the words of both men.
Nisargadatta's teaching was simple and most of his written works seem
to take the form of transcriptions of Q&A sessions, which means that
there's quite a bit of repetition and contradiction, both of which are
no doubt unavoidable in situ. Nonetheless, his words are extremely
clear and powerful at times, and I, for one, would heartily recommend
giving him a go if you haven't already. Here's a link to an online
(and free) archive of I AM THAT:

The discussions about Self and how it is dependent upon the Supreme
are completely in line with Wolff's position. The Supreme is evidently
the High Indifference. There's also an archive of Shankara's works,
too, amongst others.
One other writer whom I've found to be supportive of Wolff's ultimate
philosophical perspective is Douglas Harding. It took me a while to
realize this, as most of his books are written in a way that makes
them seem much less profound than they actually are! However, his
"magnus opus" was "The Hierarchy of Heaven and Earth". And it's
wonderful. It's also truly unique in its style and delivery. It took
me a while to realize that he's saying the same thing as Wolff (and
others), but it's well worth a look, in my opinion. The only trouble
is getting hold if it....
