161. prApyAntharaththukku anRenkai.
The recitation of this mantra is for gaining service and nothing else.
Sri PBA Swami's Sarartha Deepikai:
What is gathered from the fact that the means is described in the first part of the mantra and in this second part the goal is described?
The means described in the first part can give many things. Therefore, the goal described states that this means is not meant to gain anything but service at His divine feet.
