tayor iti anīlānutpalavyudāsayoḥ / naiva kācid vāstavī tayor ādheyatā sambhavati nīrūpasya kvacid avasthānāsambhavāt yathā vandhyāputrasya iti bhāvaḥ //
"Of these two" means "of the exclusion of non-blue and the exclusion of non-lotus." No real inherence whatsoever of these two is possible, because something formless cannot exist anywhere, just like a barren woman's son - this is the meaning.
