Sutra:
140. ithu thAn para vyUha vibavangaL pOlanRikkE kaNNAlE kANalAmpadi irukkum.

141. ivaiyellAm namakku namperumAL pakkalilE kANalAm.

Meaning:
140. This archa form, unlike the other forms of the Lord such as para, vyUha and vibhava which are not of immediate help, is available to our eyes constantly.

141. All the qualities described above that we would like to see can be seen in Namperumal.

Sri PBA Swami's Sarartha Deepikai:
The para and vyUha forms of the Lord are not visible to us because they are separated from us spatially. The vibhava forms of the Lord are not visible to us because they are separated from us by time. Unlike these, the archa form of the Lord is always with us and is always visible to our eyes.

And in this form of the Lord (in Lord Sri Ranganatha), all the qualities described before, can be seen.
