It seems I want to both thumbs up and thumbs down the question but would that not just cancel out each other, and be all as was. It turns out to be all logical and 'common' sense but the why of it all is even more simple and incredibly beautiful.
About Relativity though! If mass and energy were equal then everything in the long would be equal as long as we don't attach or identify to it's segmented or isolated parts.
With many of the decisions taken in life is the note of that little voice within, that seems to always want to point out which path leaves the cleanness in our heart. In fact I would say that it would be with us at all times, if it were us who could perfect 'being with it'. Those who try, are those who make the worst liars and certainly can't pull it off eye to eye, however those that are the most adept at leading people astray are those who have ignored that voice for so long that they now have become nearly oblivious to it, excepting in it's very most loudest of times. The non adept feels that pain and dark cloud enveloping over the heart which is revealed through the eyes. The eyes of the listener relays this in turn to their own heart and now the question becomes theirs. Presuming it a very plausible lie, they now must decide what they listen to, is it their heart or their mind. It is the heart within us that recognizes the heart within others and without question, aligns with it yet it is still the 'the lesser self that's given the choice of what to follow. It is to me no other than John's 1-9, 'the true Light which lighteth every man', or Jeremiah's 31-33, God's law he wrote in men's heart'... that we choose to listen to, or not.
The question of where we stop and God starts 'within the heart' to me can't be answered for it contains the presumption of us being in the heart which I do not agree with. In not knowing (and I don't mean believing), I meaning 'Knowing', who we truly are, is in it's self, pretending or living a lie. We all know (not consciously) but deep inside our 'Heart' the truth but have chosen to pretend 'man' and that we are separate and apart from God. This was our choice, and was granted... yet within the heart is also an exit door out of this... The identity we now presume of ourself is hardly more than imagination that's constantly seeking something to ground it's self to. It's constantly seeking self justification, approval and something to attach to. It literally is the inevitable void that we must exist in when we pretend we are who we are not. It's in this sense, that the 'we' referred to is not in the heart, but instead it's the heart that leads us to the right place. In another sense though, Mindblade16, you are also correct for the higher self 'we', is none other than who (within you) came up the 'very real' question in the first place and is the spark (or true light) within us all. To both the "believers and the nonbelievers", I ask from where within has the question arisen? A take off from that is, just whoever do you think was the true author of our very very highest aspirations and our most most rightous inherant sense of real truth and justice that we yearn for. This also has been written and reverberates within our most deepest parts and is, no mistake!
