Therefore it is appropriate that this Sankara also gives a special niche for the name Narayana. Thus it is clear that the Acharya has referred to the great causal principle of the Jagat by the name NARAYANA.
So, when he intends that the namaskaras performed to us must be conveyed to the Jagat-Karana-Vastu, he instructs: Convey to Narayana. And to carry out the instruction, he has made a rule, which appears easy on the face of it.
Only that Narayana, who has created all this and has endowed all this with vital energy (sakthi), has the "right" to accept all the namaskaras. Namaskara to any deity goes to Kesava.
We recite the sloka: Sarva Deva Namaskara Kesavam Pratigachhati. When namaskaras performed to the deities go only to HIM, how can namaskaras performed to ordinary people belong to them?
All these namaskaras also go to HIM only. It is that we have been asked to always remember when namakaras are performed to us.
In order that we do not "misappropriate" the namaskaras rightfully belonging to HIM only and make sure that the namaskara is duly redirected to HIM, the Acharya has most kindly defined a rule for us – a rule, which as I said earlier, is seemingly easy.
The rule is that when someone performs a namaskara to us, we should say "Narayana, Narayana". If that is done, when the name is uttered, does not the person immediately come to mind?
Here Narayana is that person. The moment He comes to mind, the thought that all namaskarams belong to HIM and we should not take away what is HIS right and possession also will come to mind; and we will convey the namaskara to the right place.
That is why, the Acharya prescribed remembering Narayana (Narayana Smaranam). The smaranam is important.When we utter the word Narayana, it is only speech (vachanam). It is not remembering (smaranam).
