Since truths are simply chemically enhanced perceptions that warm the synapses, altering the chemical makeup is changing reality. This is also the true efficacy of prayer.
Inside our brains, the mind is drugs making up those realities and that, is what we believe is true and real. Religion is the result of a race—who can dispense the most candy by playing on the highs and lows of human survival. More candy—more truth. More trauma, more candy. They thrive on it.
By altering what nature has limited us to see by evolving for survival, adding more fizz is simply expanding our sphere of awareness. So, no perception is anymore real than any other, just more acute—and acute translates to truth.
Heaven would be simply endless endorphins in a stupor of pleasure (for the eternal body) resurrected in its perfect state, able to dispense at-will, whatever you will.
