If Libra was becoming more spiritually aware and beyond what the physical body can affect, the fact that as he rose he became corporeal to the Sphere of Gods could just be the matter=spiritual equalization some emanationist philosophies apply.
That is to say, what is spiritual and transcendent is to the realm below that is physical from its own point of view, but that spiritual realm is physical to itself and what lies above, which that which lies above seeing the two realms below as physical.
So, it's possible to in fact use Libra's ascension to showcase it is an emanationist cosmology with the larger reality being transcendental to what lies below, while being physical and limited to what lies above.
