Sutra:
65. iththaal thanakkum piRarkkum uriththanRenkiRathu.

Meaning:
The ukAram that shows anya sEshatva nivrutti says that the soul neither belongs to another (other than Him) nor does it belong to itself.

Sri PBA Swami's Sarartha Deepikai:
The phrase "anya sEshatvam kazhikai" is further explained here. It is not just that the soul should not be enslaved to another samsari who is like itself. It also means that the soul should not be enslaved to itself. The term anya includes the self as well, as the self belongs to the same category as the anya's. anya seshatva nivrutti includes the removal of enslavement to the self also; there is no need to show a separate effort for the same. SvasEshatva nivrutti is included therefore through the mening of anya sEshatva nivrutti in the ukAram.

Thus far, the meanings of ukAram have been explained.
