101. antharyAmithvamum upAyathvamum upEyathvamumAgavumAm.
The three qualities of antaryAmitvam, upAyatvam and upEyatvam are also derived from the meanings using the two samAsas (other than deriving the two qualities of paratvam and Saulabhyam).
Sri PBA Swami's Sarartha Deepikai:
It was said before that from the meanings of nArAyaNa using the two samAsas (tapurusha samAsa and bahuvrIhi samAsa), two divine qualities of the Lord can be derived viz. paratvam and Saulabhyam. Here it is being said that other than these two qualities, the two samAsas also show three qualities viz. antaryAmitvam, upAyatvam and upEyatvam.
The fact that He resides within all eternal beings shows His quality of antaryAmitvam. The ayana term can be derived out of karaNe vyutpatti (derived from the action) or karmaNi vyutpatti (derived from being connected to the action). Through the former, He is seen as the upAya (the means) and through the latter, He is seen as the upEya (the goal).
