“Shukadeva Gosvami, after citing the example of Maharaja Khatvanga, who prepared himself for the next life within a very short time, encouraged Maharaja Parikshit by saying that since he still had seven days at his disposal, he could easily take advantage of the time to prepare himself for the next life.” (Shrila Prabhupada, Shrimad Bhagavatam, 2.1.14 Purport)
