Translation: 
Please tell us how we may constantly remember Your lotus feet, though we continue in the cycle of birth and death in this world.
Purport: 

One can constantly remember the Lord only by His mercy. Such remembrance is the easy method to obtain supreme liberation, as explained in Bhagavad-gītā (8.14):

ananya-cetāḥ satataṁ
 yo māṁ smarati nityaśaḥ
tasyāhaṁ sulabhaḥ pārtha
 nitya-yuktasya yoginaḥ

“For one who always remembers Me without deviation, I am easy to obtain, O son of Pṛthā, because of his constant engagement in devotional service.”

The words api saṁsaratām iha indicate that the kings were approaching Lord Kṛṣṇa not merely for liberation but rather for the boon of always being able to remember His lotus feet. Such constant remembrance is a symptom of love, and love of Godhead is the actual goal of life.
