PURPORT

As stated in Srimad-Bhagavatam (5.6.18): muktim dadati karhicit. Srila Sukadeva Gosvami told Maharaja Pariksit that Krsna readily grants liberation but does not very readily grant perfection in devotional service. This means that Krsna wants to see that a devotee is actually sincere and serious and that he does not have ulterior motives. If this is the case, devotional service can very easily be successful; otherwise it is very difficult to obtain from the Supreme Personality of Godhead. This verse appears in the Bhakti-rasamrta-sindhu (1.1.35).
