Sutra:
54. akAraththilE kalyANa guNankaLais sollukaiyAlE intha sEshathvamum guNaththAlE vanthathu.

Meaning:
The akAram describes Sriman Narayana as the rakshaka. His kalyANa guNas are the reason behind His rakshaNam. The bhagavat sEshatvam that is described by the hidden case is also because of the kalyANa guNas.

Sri PBA Swami's Sarartha Deepikai:
It is true that on selected situations being enslaved brings about happiness in this world. But this is based on certain guNas that are present in the lord which the person who is enslaved enjoys. So, is there anything like that in the bhagavat sEshatvam described by the hidden fourth case in the akAram?

Sri Pillai Lokacharya answers yes. Because the akAram describes His kalyAna guNas, the sEshatvam also comes out of the same guNas. Previously, it was shown that the akAram describes the Lord as rakshaka. This rakshaNam is based on His kalyANa guNas. Therefore, the bhagavat sEshatvam, that is described by the hidden fourth case in the akAram, is also the result of His kalyANa guNas. Therefore (that is, because it arises due to the delightful kalyANa guNas), the sEshatvam also brings about happiness.
