yudhishthirah -- King Yudhishthira; tu -- but; tam -- Him, Lord Balarama; drishtva -- seeing; yamau -- the twin brothers, Nakula and Sahadeva; krishna-arjunau -- Lord Krishna and Arjuna; api -- also; abhivadya -- offering obeisances; abhavan -- they were; tushnim -- silent; kim -- what; vivakshuh -- intending to say; iha -- here; agatah -- has come.
Srila Prabhupada writes, "The reason why they were silent was that Lord Balarama was somewhat affectionate toward Duryodhana, and Duryodhana had learned from Balaramaji the art of fighting with a club. Thus, when the fighting was going on, King Yudhishthira and the others thought that Balarama might have come there to say something in favor of Duryodhana, and therefore they remained silent."
