Gnanam theritharuL Arunachala
Arunachala, even though I didn’t have enough ‘gnana’ (wisdom) to find (obtain/have) you, I was consumed with the insatiable desire to reach you. Please make sure the desire does not weaken so I can reach you through atma vichara (self enquiry).
When you want something badly and the desired object eludes you, it’s natural for the desire to dwindle and weaken. When the desire to reach god is strong but there is insufficient knowledge/wisdom, then the desire weakens. For the weakness to be removed, Arunachala’s grace is essential, which in turn requires one to do self enquiry, for which His grace is needed. Like Saint Manickavasagar said, ‘avan aruLale avan thaaL vanangi’ meaning by His grace worship His feet. That is why Bhagavan is saying, ‘gnanam theritharuL’, meaning show me the knowledge.
Note: ‘gnanam’ usually refers to wisdom, loosely could be taken to mean knowledge.
