One of our previous acaryas has said that one has to feel himself to be the negative, and if he feels himself to be helpless and in need of shelter, then the positive comes to compensate and brings him up. I am inspired by that concept--that Krsna comes down and lifts up His devotee because a devotee is not demanding, and does not say, "Krsna you must do this. Rather, the devotee helplessly calls, "I am totally dependent on Your mercy, although I am unqualified for it." Krsna then sees that his devotee is not conditional, but helpless, and being the complete positive entity, He comes down to the position of the negative, the state of inadequacy, and lifts the devotee to a higher state of consciousness. That mood of utter helplessness should always be kept at every stage of a devotee's advancement in Krsna consciousness for as soon as one thinks that he is in any way advanced one's sense of dependence quickly diminishes. One also naturally loses his sense of gratitude.
