pārtha naiveha nāmutra vināśhas tasya vidyate
na hi kalyāṇa-kṛit kaśhchid durgatiṁ tāta gachchhati
O son of Prithâ, neither in this world nor in the life to come is there destruction for him; never doth any who worketh righteousness, O beloved, tread the path of woe.
In plain words: Krishna tells Arjuna, the son of Pritha, that such a person is never destroyed, not in this life or the next. Anyone who does good never ends up on a path of misery.
