In this verse the word vrddha-sevaya is very significant. Vrddha means old. Sevaya means by service. Perfect knowledge is acquired from the acaryas, or liberated souls. No one can be perfect in knowledge without being trained by the parampara system. Prthu Maharaja was completely trained in that line; therefore he did not deserve to be considered an ordinary man. An ordinary man, who has only a conception of bodily existence, is always bewildered by the modes of material nature.
