Srila Bhaktivinoda Thakura writes in his book,Bhagavata-arka-marici-mala,
“First I will first explain
vaidhi-bhakti, and then raganuga-bhakti.”
He quotes the following verse:
nr-deham adyam su-labham su-durlabham
plavam su-kalpam guru-karnadharam
mayanukulena nabhasvateritam
puman bhavabdhim na taret sa atma-ha
[“The human body, which can award all benefit in life, is automatically obtained by the laws of nature, although it is a very rare achievement. This human body can be compared to a perfectly constructed boat having the spiritual master as the captain and the instructions of the Personality of Godhead as favorable winds impelling it on its course. Considering all these advantages, a human being who does not utilize his human life to cross the ocean of material existence must be considered the killer of his own soul.” (Srimad-Bhagavatam 11.20.17)]
In this verse Srila Sukadeva Gosvami is indicating to Maharaja Pariksit, “Katvanga Maharaja attained Krsna-bhakti and went to Vaikuntha in only twelve minutes. You have seven days left to live, and so you can achieve more than he did.”
