In the course of this discussion I have discovered this little gem which probably explains much of dispute that we're having.

There is no law of rta. There is rta and rta is harmony; but this harmony is not subjected to any ulterior law. There is no mind behind. To live in a rtic universe represents a fundamental human experience different from that of believing [we] live in a logical world or in a universe, governed by law ... This is what the upanishads will try to qualify later. Being is free, ultimately even from thinking. No need of ethical norms at the ultimate level. No need of fear, 'Angst', anxiety, regarding ultimate questions. Rta is there, but not as a refuge. No need to control everything, to be certain of all things, to know everything.

So because Rta proposes a harmonic order that is beyond thought it is inexplicable.
