The Veda’s cage is its epistemology in its own experiential framework rather than supposed philosophical proclivities, which are vast, including experiences philosophically beyond the personal consciousness of the brain, mind, or person.
It asks, if nothing can be known beyond my consciousness, what is God but the last barrier, the last walls or rather the horizon to my own consciousness? This God being named the infinite consciousness.
Based on this question lies its entire foundation.
If consciousness is a product of the human mind or brain, the experience of consciousness an experience of the brain, the remainder is philosophical foray and beyond the scope of normal or even advanced human meditation practice.
Vedic thought is imprisoned in its own epistemology in the sphere of its experiences for when backed into the corners of scientific scrutiny relies on the simple and non-faith based, reason-based commercialized acknowledgement of consciousness and its nature as the only knowable thing to uphold its vast world.
And if consciousness, the one based on the person be centered in the brain, be proved to be so, it denies the whole philosophical dynamic and framework from top to bottom. The Veda relies not on God to affirm its world but on the existence of the personal consciousness as being not in the person or brain itself, the adventure to God being based on inquiry into consciousness to the point of direct contact and awareness without faith but through this inquiry.
In Christianity, the experience of God relies not on the mechanism and descriptions of our ability to know God but on God Himself and knowing Him as Jesus Christ.
Jesus Christ is not the mechanism of our knowing God in this context, for that is a theological reality, and for this context an argument as such would be called a fallacy of the ambiguous term disguised as mere stylism, another flaw, but in truth being stylism and falsity in addition disguised as truth not only in general but Christian truth. It is using a truth of Christianity itself, in ambiguity, to contradict a claim in defense of Christianity, its innocence and coherence as faith based.
