SB 10.73.15
tam nah samadisopayam
yena te caranabjayoh
smrtir yatha na viramed
api samsaratam iha
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-gita (8.14):
ananya-cetah satatam
yo mam smarati nityasah
tasyaham sulabhah partha
nitya-yuktasya yoginah
“For one who always remembers Me without deviation, I am easy to obtain, O son of Prtha, because of his constant engagement in devotional service.”
The words api samsaratam iha indicate that the kings were approaching Lord Krsna 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.
