The height of the quality of saulabhyam, which is in the series of qualities described above, is the archa form of the Lord.
Sri PBA Swami's Sarartha Deepikai:
Amongst the qualities described above, the quality of saulabhyam is very important. And the height of that quality is seen in the archa form, where He takes as His form something that His devotees like and resides all the time in it for them.
