If you feel at all indebted to me then you should preach vigorously like me. That is the proper way to repay me. Of course, no one can repay the debt to the spiritual master, but the spiritual master is very much pleased by such an attitude by the disciple. In the Bhagavad-gita it is said, vyavasayatmika buddhir ekeha kuru nandana (BG 2.41), "Those who are on this path are resolute in purpose, and their aim is one." Our only business is to be fixed up in devotional service by pleasing the spiritual master. Those who are not fixed up they have various lines of action (eka means 'one' and bahu means 'many').
The real ocean of mercy is Krsna and it is the duty of the spiritual master to tell his disciple to come to the ocean and be happy. The spiritual master's duty is to lead the disciple to this ocean. I am trying my best and if you try to follow surely you will benefit.
Bhaktivinode Thakura has sung, "Krsna sei tomara, krsna dite para, tomara sakati ache. Ami ta'kangala, krsna krsna boli, dhai tava pache pache." "Krsna is yours and you have the power to give Him to anyone you wish. I am poor and wretched and running behind you shouting Krsna, Krsna!"
Krsna is unlimited, no one can catch Him, but if someone follows the parampara, he agrees to be captured. Everyone is afraid of Krsna, but Krsna is afraid of Mother Yasoda. That is Krsna's special mercy.
