The word paramam is explained thus by Parasara Muni: one who is full in six opulences, who has full strength, full fame, wealth, knowledge, beauty and renunciation, is paramam, or the Supreme Personality of Godhead. While Krsna was present on this earth, He displayed all six opulences. Therefore great sages like Parasara Muni have all accepted Krsna as the Supreme Personality of Godhead. Now Krsna is instructing Arjuna in more confidential knowledge of His opulences and His work. Previously, beginning with the Seventh Chapter, the Lord already explained His different energies and how they are acting. Now in this chapter He explains His specific opulences to Arjuna. In the previous chapter he has clearly explained His different energies to establish devotion in firm conviction. Again in this chapter He tells Arjuna about His manifestations and various opulences.
