Sutra:
73. iththAl *thAmaraiyAL kELvan oruvanaiyE nOkkum uNarvenRathAyiRRu.

Meaning:
With this praNavam, as per Sri Poygai Azhvar's Srisookti, the relationship between the jIvAtma and the paramAtma is told.

Sri PBA Swami's Sarartha Deepikai:
Previously it was told that when He is protecting the jIvas it is required that Lakshmi be present and therefore the Sri sambandham is included in the akAram (sutra 40). Therefore, in the relationship between the jIvAtma and the paramAtma, the sEshi is now shown as the Divya Dhampati (Divine Couple).

The praNavam can also be chanted through Poygai Azhvar's divine words "oNdAmaraiyAL kELvan oruvanaiyE nOkkum uNarvu". Through thAmaraiyAL kELvan, Sriman Narayana who is the meaning of akAram and who is the sEshi is told. Through oruvanaiyE nOkkum, the Atma's sEshatvam to the one Lord and no one else, which is shown by the fourth case and the ukAram, is told. Through uNarvu, the Atma which is shown by the makAram, whose nature is knowledge and whose quality is that sEshatvam, is told.

Therefore if one wishes to chant the praNavam while bringing out the Lakshmi sambandham, then they can chant this pasuram of Poygai Azhvar.
