God wants nothing but our good. We ourselves, however, falling into delusion, may reject His love. Gaze not at darkness, but at the light. There is no point in cowering before God's wrath, which in any case is entirely imaginary. Still less point is there in railing angrily at oneself.
Mistakes do occur in life, after all.
Instead of raging against oneself, one's remorse should redirect energy toward a solution. Krishna described the downward path into delusion. Let us reconsider his words from an opposite point of view. From attraction grows desire. From infatuation ensues forgetfulness of the higher Self.
