Came across the wiki article on Brahman whilst researching for a uni essay (on hindu philosophy.) please see here: http://en.wikipedia.org/wiki/Brahman
towards the bottom of the page
There is a section on 'Brahman in Earliest Buddhism' (even though it talks under the same section about the later Mahayana Lalitavistara and Shurangama Sutras I'm not sure if they count as all that early???)
There are a number of references to places in the Nikayas where it interpolates the word 'Brahman' in place of Brahma (which actually just means 'divine' right? without any meaning of the cosmic Brahman.)
If I'm understanding it right, it seems to want to argue the Buddha was teaching some kind of Vedanta and claiming the 'Brahma' in brahmavihara is really talking about Brahman!
It's not very well referenced or anything, worryingly just a reference to an obscure german paper, a theosophist article amongst over things.
Would like to see if you can make any sense of it - I get the idea it's total nonsense! One of the first times I've come across something which appears so misleading on wiki.
Ok thanks very much everyone
