There are no assumptions on my part in this case as I speak from position of self-knowledge. That is, I know who I am. Thus, if I give the authors of all those traditions in question the benefit of doubt that they knew themselves and, indeed, knew what they were talking about, it is the only possible way of interpretation of said writings in order for them to make any sense at all (that, or if they meant something different, they are patently false).
And just for the record, I found out that, from times immemorial, people described the absolute in very similar ways to what became clear to me after self-realization. In other words, I was surprised to discover that what self-realization revealed to me was already an established knowledge in many different traditions. Frankly, before I knew myself, all spiritual literature (particularly the ancient one) was utter gibberish to me and my appreciation came only later, after the fact.
Know thyself, Graham. And all your questions will be answered.
