Sutra:
175. prAptha vishayaththil kainkaryamiRE raSippadhu.

Meaning:
In following one's nature and seeking the correct end, it is service that will tasteful.

Sri PBA Swami's Sarartha Deepikai:
In the sastras, service toward the wrong end is rejected. In contrast, toward the right goal, it is service that is of delight. Therefore, saying that the quality of Lordship is the one that is important here, is appropriate.
