Haridasa Thakura is mentioned here as the most learned scholar, parama-vidvan. Actually, the most important science to know is the science of getting out of the clutches of material existence. Anyone who knows this science must be considered the greatest learned person. Anyone who knows the temporary situation of this material world and is expert in achieving a permanent situation in the spiritual world, who knows that the Supreme Personality of Godhead is beyond the jurisdiction of our experimental knowledge, is understood to be the most learned scholar. Haridasa Thakura knew this science perfectly. Therefore, he is described in this connection as parama-vidvan. He personally preached the importance of chanting the Hare Krsna maha-mantra, which is approved by the revealed scriptures.

There are nine different processes of devotional service to Krsna, the most important being sravanam kirtanam-hearing and chanting. Haridasa Thakura knew this science very well, and he can therefore be called, technically, sarva-sastradhiti. Anyone who has learned the essence of all the Vedic scripture is to be known as a first-class educated person, with full knowledge of all sastra.
