Lord Krsna is everything to the unalloyed devotees like the Pandavas. The Lord was for them the Supreme Lord, the spiritual master, the worshipable Deity, the guide, the chariot driver, the friend, the servant, the messenger and everything they could conceive of. And thus the Lord also reciprocated the feelings of the Pandavas. Maharaja Pariksit, as a pure devotee of the Lord, could appreciate the Lord's transcendental reciprocation of the feelings of His devotees, and thus he himself also was overwhelmed with the dealings of the Lord. Simply by appreciating the dealings of the Lord with His pure devotees, one can attain salvation. The Lord's dealings with His devotees appear to be ordinary human dealings, but one who knows them in truth becomes at once eligible to go back home, back to Godhead. The Pandavas were so malleable to the will of the Lord that they could sacrifice any amount of energy for the service of the Lord, and by such unalloyed determination they could secure the Lord's mercy in any shape they desired.
