The more we experience God within our hearts, the greater our awareness becomes of a God "the heavens cannot contain" and how insignificant we really are and the love He has for each one of us.
That which you think is "experiencing" God in your heart is the same "experience" that a man gets in riding a roller coaster or getting himself hyped up to play a sport. It's not God, it's yourself. Even if you did experience sensory delight in prayer, this is but the milk of an infant in the spiritual life. To claim that more of this is indicative of our greater union with God is foolish. Your entire conception of the spiritual life is radically opposed to the spiritual masters. I must say that I am not surprised given the universal disorientation of souls. I am sure you are very sincere in your beliefs, but they are untested, unwise and extraordinarily dangerous. It's not as if the ordinary way of sanctity is negotiable, it's general outlines are morally necessary to reach union with God. A denial of this is a denial of our true spiritual condition.
