I agree the part about God is not our order supplier; I've had loads of desires in my past life.
Its like sometimes you may think or I do anyway 'why do I bother?' I feel that a lot. I think its cause of forgetting about Gods power. He is Lord not me, I am not all in all. I am small He is big but also this is not a bad thing I feel.
For me it feels good to ask Krishna not for material things but devotion to Him, because then at least I am using the propensity to ask which I need to do.
Over the years I have gained sort of a patient approach, I know I have to wait. When that mercy descends or how it did, who what when where? Its devotee's mercy they are even more merciful than Krsna cause they are Krsna devotees, if you want to ask something from Krishna ask that you can serve a pure devotee.
