BG Chap 18 - The result of incorrect and correct renunciation
Those who do not renounce in the prescribed way have the results – desirable, undesirable and mixed – accrue after death. They get results in the form of heavenly enjoyment (desirable), hellish suffering (undesirable) or human birth (mixed) in the next life.
Those who renounce correctly attain liberation by the jñana contained within the actions. A person in Kṛṣṇa consciousness acting in knowledge of his relationship with Kṛṣṇa is always liberated. Therefore he does not have to enjoy or suffer the results of his acts after death.
