You seem to be saying that God cares about our religious practices because they "echo in eternity" and impact the universe.

If you're saying that the whole intellectual, theological side of religion is part of our "fallen" nature, whereas God cares more about intentions and practices than dogmas, you're close to agreeing with the article's main point.

But the question is whether religious practices are more like notational variations so that God would care about the intentions but not the details of the rituals. That distinction, too, would lead to my interpretation of Gandhi's point.

And whether God would know everything isn't the same as asking whether he'd care about everything. Why wouldn't God be more like a celebrity who wouldn't care about the little people?

To suggest that God cares about our intentions seems vain and naïve. What would an 11D tesseract have to do with humanoid personhood? That mysticism already entails atheism, as in the denial of the exoteric theist's conception of God.
