Bhagavad Gita · Chapter 6: The Path of Meditation
Bhagavad Gita 6.40
पार्थ नैवेह नामुत्र विनाशस्तस्य विद्यते ।
नहि कल्याणकृत्कश्चिद्दुर्गतिं तात गच्छति ॥
pārtha naiveha nāmutra vināśastasya vidyate | nahi kalyāṇakṛtkaściddurgatiṃ tāta gacchati ||
Arjuna, neither here nor hereafter is there destruction for such a person. No one who does good, my dear friend, ever comes to a bad end.
Modern context
This is the answer, and it is one of the warmest lines in the Gita. No one who does good ever comes to a bad end. Not in this world, not in the next. Krishna calls Arjuna tata, an affectionate word used for a son or a dear one. The message is that sincere effort is never lost. Even a half-finished spiritual life leaves a person better than they were. Nothing given to the good is wasted.
