Bhagavad Gita · 6.40

श्रीभगवानुवाचपार्थ नैवेह नामुत्र विनाशस्तस्य विद्यते।न हि कल्याणकृत्कश्चिद्दुर्गतिं तात गच्छति॥

śhrī bhagavān uvācha pārtha naiveha nāmutra vināśhas tasya vidyate na hi kalyāṇa-kṛt kaśhchid durgatiṁ tāta gachchhati

The Blessed Lord said: O Partha, neither in this world nor the next is there destruction for such a person. No one who does good, My dear friend, ever comes to an evil end.
