Sutra:

Meaning:
In this world, when a man hires a servant to do work in his house, he writes a contract that the servant will do his bidding but does not explicitly note that the servant should do the bidding of his wife. Nevertheless, we see that the servant does the work as ordered by the wife. Similarly, we are also enslaved to Sri Mahalakshmi.

Sri PBA Swami's Sarartha Deepikai:
Is it not said in the praNavam that the chetana is enslaved to the Lord - so, how can one say that he is also enslaved to Mahalaskshmi?

This is answered using an example from this world. When a rich person hires some servants to do work at his home, there will usually be a contract written. This contract is called AvaNai Olai. When this contract is written, the man would typically have it written in his name and not in his wife's name. Nevertheless, it is very often seen that the servant ends up doing mostly the bidding of the wife. Similarly, while the akAram only mentions that we are enslaved to Him, it does not preclude that we are also enslaved to pirAtti.
