Bhagavad Gita
18.15

शरीरवाङ्मनोभिर्यत्कर्म प्रारभते नरः | न्याय्यं वा विपरीतं वा पञ्चैते तस्य हेतवः ||

śarīra-vāṅ-manobhir yat karma prārabhate naraḥ nyāyyaṁ vā viparītaṁ vā pañcaite tasya hetavaḥ

Translation

Whatever action a person performs with the body, speech, or mind — whether right or wrong — these five are its causes.

Interpretation

The five causes apply universally: to every action of body, speech, or mind — whether the action is right (nyayyam — proper, righteous) or wrong (viparitam — contrary, unrighteous). Even mistaken or harmful actions arise from the interplay of these five factors. This removes both arrogance about virtuous acts ('I alone did this good') and excessive self-blame about errors ('I alone caused this harm'). Understanding the five causes brings equanimity toward both success and failure, both virtue and error.
