“Arjuna! Kāmya karmas are subject to ‘abhikramanāśa’. Niṣkāma karmas are not subject to abhikramanāśa. This is the difference between sakāma and niṣkāma karmas. In kāmya karma one must be ready even for punishment; in niṣkāma karma there are no such punishments. Desire for the fruit is the cause of saṃsāra; renunciation of the fruit is the cause of Mokṣa. Even if one who follows the path of niṣkāma karma yoga cannot achieve siddhi in that very birth, the karma he has done is not wasted. Its fruit will ripen, if not now, then in the birth that follows. He can surely reach his goal. So keep your right in karma alone, but do not keep a right in the fruit of karma.
