Karadayan Nonbu is adhered seeking protection of one's husband. It does not seem to have any vaideekam significance. Further when one has had Bharanyasam, seeking the pleasures for this life whether it is for a brother or husband, I feel it is again taking us away from our path to the ultimate when we have totally surrendered to Narayana. Accepted that we have certain duties to be performed towards our children and towards our parents. Our actions I feel should not be self-centred. Otherwise we will be getting caught in the whirlpool of Samsara and materialism. Gods are not businessmen to accept a nonbu and give longevity to husband. Well these are just my thoughts.
