Meaning :
In this verse, SrI kulaSEkharar talks to people of the world at large. He asks them to listen to the cure recommended by great yOgi-s and sages like yAGYavalkya against the cycles of birth and death that cEtana-s are subject to as samsArin-s.
AzhvAr points out that the medicine recommended by the revered sages is a nectar-like drink known as SrI-kRshNa. That shining nectar which is immeasurable in its qualities will cure one’s samsAric illnesses permanently. AzhvAr equates SrI kRshNa to the powerful medicine which will cure the disease of recurring cycles of birth and death. He says the medicine has been time-tested by great sages and it is the panacea for the disease of samsAra.
