At the end of our life, our own service will be judged but more important, is the service of our spiritual master, who is requesting Krsna, “Please accept him, he didn’t do well but accept him anyway.”
This is actually how it works. Thus Srila Prabhupada is praying for all of us and saying, “Please take them all back to Godhead. I know everything but still… Please take them back to Godhead.”
Then what can Krsna do, because Prabhupada has done such service that Krsna has become so indebted; what can he do!? So when Srila Prabhupada is asking then, “All right, let him go.”
So mercy is a major factor and thus we must look for that mercy. Therefore, we must always turn to our spiritual master. It’s not that the spiritual master should turn to us, we should turn to him for shelter!
