शरीरवाङ्मनोभिर्यत्कर्म प्रारभते नरः। न्याय्यं वा विपरीतं वा पञ्चैते तस्य हेतवः ॥

śharīra-vāṅ-manobhir yat karma prārabhate naraḥ nyāyyaṁ vā viparītaṁ vā pañchaite tasya hetavaḥ

Whatever action a man performeth by his body, speech and mind, whether right or the reverse, these five are the cause thereof.

In plain words: Krishna says every action a person does with body, speech or mind, right or wrong, comes from these five causes together.
