It was difficult to sustain a physical body when the whole world was trying to rip his soul away.
Exposing his soul to the erosion was too risky. Even if it could take away the of the burden on keeping himself together if he just fought in his soul form, Varian decided it was not worth the risk.

He searched, searched and searched.
A week passed or perhaps two.
There was nothing to be found.
