Arjuna began to speak: "O King! The Supreme Personality of Godhead, Hari, who treated me exactly like an intimate friend, has left me alone. Thus my astounding power, which astonished even the demigods, is no longer with me.
Suta Gosvami said: Arjuna, the celebrated friend of Lord Krsna, was grief-stricken because of his strong feeling of separation from Krsna, over and above all Maharaja Yudhisthira's speculative inquiries.
Being too much aggrieved, Arjuna practically became choked up, and therefore it was not possible for him to reply properly to the various speculative inquiries of Maharaja Yudhisthira.
