Grounding reason: states of consciousness and epistemology

This logi isn't really a worked-out line of thought; it's more a request or invitation to help me define the parameters of an inquiry that's forming in my mind.

The starting point for this logi is some thoughts I've been having about certain schools of philosophy whose epistemologies are not entirely ratiocinative in character. That is to say, I think most of us (though I'm not trained in philosophy) tend to think about epistemology as something to be gone about in a more-or-less analytic or logical fashion - an attempt to prove or deduce what it is we absolutely can or must know.

However, there are some schools of thought - I'm thinking in particular of post-Hellenistic Stoicism, certain flavours of Buddhism, and perhaps the wilder fringes of Neo-Platonism - that appear to me to take ratiocination alone as an inadequate or even dangerous basis for epistemology. Reason, if exercised without the appropriate emotional/psychological/spiritual grounding, is understood as potentially misleading. And so other, if not irrational, at least arational or pararational, techniques need to be brought into play to somehow ground reason, or balance out the organism. And what I'm curious about is how these arational aspects of the psyche are conceptualised and/or ideally altered in such traditions.

So I suppose what I'm asking is - does the above characterisation of Stoicism/Buddhism/Neoplatonism seem reasonable to other logi-ers? Do other schools fit the bill? And where I might I go to find out more? Or am I now veering rather far outside philosophy into what is now more properly dealt with under the heading of psychology?
