Sutra:
40. rakshikkum pOthu pirAtti sannithi vENdukaiyAlE ithilE Sri Sambantham anuSanthEyam.

Meaning:
At the point where He protects the chetanas, as it is imperative that pirAtti be with Him, in the akAram that shows Him as sarva rakshaka Her association has to be included.

Sri PBA Swami's Sarartha Deepikai:
Thus far, in establishing the meaning of the first akshara of praNavam which is akAram, the meaning of akAram which is Him, the meaning of protection offered by Him, the different types of protection based on status of the souls, and that He is the only protector have been shown. Now, it is shown that Lakshmi sambantham is included in the akAram.

In providing rakshaNam, while He is capable of providing it without using any help and all by Himself, the Sastras say that He does it in the company of Sri MahaLakshmi. There are many several pramanas for this such as "lakshmyA saha hrushIkesO devyA kAruNyarUpaya, rakshakas sarva siddhAnte vedAntebi cha gIyate" (all Sastras show that the Lord protects only along with Lakshmi who is compassion personified).

There is a possibility, when a chetana comes before Him, due to the the chetana's countless sins and due to His own svAtantryam (independence), that He could reject the chetana. Therefore, Her presence with Him which generates compassion in Him is required during the time that He provides rakshaNam. Thus, Her sambandham to Him has to be thought of when the akAram is explained as showing His rakshgatvam. That is, the meaning of akAram is Sriman Narayana who is never separated from His consort.

When Narayana is thought of, He is thought of as Sriman Narayana; so why does it have to be explicitly said that Sri Sambandham should also be included in that?

This is true; nevertheless, it is appropriate to remind everyone of that sambandham.
