Sutra:

Meaning:
The quality of vAtsalyam will help the chetana not fear looking at his own errors. The quality of svAmitvam will help the chetana be sure that He will take care of him. The quality of sausIlyam will help the chetana not do naicyAnusandAnam looking at His great glory and stay away from Him. The quality of saulabhyam will help the chetana see Him directly and reach Him. The qualities of gyAna and shakti will help remove the obstacles to reaching Him.

Sri PBA Swami's Sarartha Deepikai:
How are these qualities brought forth by the nArAyaNa term here?

Vatsalyam is brought forth to make sure that the chetana does not fear seeing the enormous sins that he has committed. This quality is seen in a cow shown toward its calf. That is, considering the dirt on the calf as sweet, giving milk for its growth and fighting off its enemies with horns and hooves. Similarly, He too looks at the chetanas errors as good ("ennadiyAr athu seyyAr seythArEl nanRu seythAr"), takes care of the chetanas through His qualities ("pAlE pOl sIr") and always protects them ("na tyajeyam kathanjcana").

Svamitvam is brought forth so that the chetana does not have to fear if He will take care of him. Svamitvam means that the master truly owns that which belongs to him. Even if the chetana turns his sface away from Him, He will stay focused on him and maintain His relationship to him. Since the loss of the chetana is His loss, the chetana can be sure that He will take care of him.

SausIlyam allows the chetana not to look at His immeasurable greatness, His lordship over both vibhUtis and his own lowliness and keep away from Him. SausIlyam is the quality due to which He mixes with everyone without looking at their nature. Therefore the chetana does not have to keep away.

Saulabhyam is the quality by which the chetana without wondering that He cannot be seen ("atIndriya"), can see Him with his own eyes and serve Him. Saulabhyam is making Himself visible to all.

The qualities of gyAna and shakti help remove the obstacles to the goal and give Himself to the chetanas. Knowledge allows Him to see the lowliness of the chetana and what he needs in order to reach Him. Having understood that, shakti helps in making it happen.
