According to Osho, in true devotion the whole ‘ledger’ of karma is surrendered; the devotee drops the sense of doership, so the arithmetic of cause-and-effect no longer governs him. Grace, not accounting, operates. If you want exact fruits of deeds, follow the karmic path; but in surrender, even karma is offered up, and the Divine assumes responsibility.
If you truly give everything to God, you stop keeping score of good and bad and let grace handle the results.
